[I] Resizable modals resize from the wrong corner and drift while resizing [superset]
GustafHultgren opened a new issue, #43320:
URL: https://github.com/apache/superset/issues/43320
### Bug description
Resizable modals in Superset — including Drill by, Drill to detail, and Chart Data / View as table — behave incorrectly when resized from any edge/corner other than the bottom-right. Not a critical issue, but might throw some users off.
## Steps to reproduce
1. Open a chart and trigger one of the affected modals (e.g. right-click a chart → "Drill by", or "View as table").
2. Try to resize the modal by dragging its top-left corner (or the left/top edges).
3. Observe the resize behavior.
### Expected behavior
Dragging the top-left corner should resize the modal by moving its top-left edge while keeping the bottom-right edge fixed, the same way resizing works on most desktop windows/dialogs.
### Actual behavior
Dragging from the top-left corner (or left/top edges) resizes the modal from the bottom-right instead — the opposite of the edge being dragged.
In addition, resizing along one axis can unexpectedly move the modal.
## Likely cause
The resize handles sit inside a draggable wrapper, and both resizing and dragging try to control the modal's position independently. Resizing from the top or left needs to reposition the modal to keep the opposite corner anchored, but the drag logic overrides that position separately — the two conflict, producing both the wrong-corner resize behavior and the occasional drift on the other axis.

<!-- Answer -->
@GustafHultgren — nice report, and your analysis of the root cause is spot-on. Here's what the code confirms:
The `Modal` component's `modalRender` wraps everything in `<Draggable>` (from `react-draggable`) as the outer element, with `<Resizable>` (from `re-resizable`) nested **inside** it [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/packages/superset-ui-core/src/components/Modal/Modal.tsx#L322-L339). Resizing from a top or left edge needs to reposition the modal's top-left corner to keep the opposite corner anchored — but `react-draggable` owns position through its own internal `transform` state. The two update position independently, so `re-resizable`'s correction gets overridden, producing the inverted-corner resize and drift you described.
Worth noting: the default config only enables `bottom`, `bottomRight`, and `right` handles [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/packages/superset-ui-core/src/components/Modal/Modal.tsx#L182-L191), so the bug only surfaces when a caller passes a custom `resizableConfig` that enables `top`, `left`, `topLeft`, etc.
**To fix this**, the key is to switch `react-draggable` to [controlled mode](https://github.com/react-grid-layout/react-draggable#controlled-vs-uncontrolled) so that resize position corrections aren't silently overridden. The approach would be to use `re-resizable`'s `onResize` callback to adjust `react-draggable`'s position in sync with the size delta — subtracting the height/width delta from `y`/`x` respectively when a `top` or `left` handle is dragged:
```tsx
const [position, setPosition] = useState({ x: 0, y: 0 });
// In Resizable onResize:
onResize={(_, direction, __, delta) => {
if (direction.includes('top')) {
setPosition(pos => ({ ...pos, y: pos.y - delta.height }));
}
if (direction.includes('left')) {
setPosition(pos => ({ ...pos, x: pos.x - delta.width }));
}
}}
// Pass to Draggable:
<Draggable position={position} onDrag={(_, data) => setPosition({ x: data.x, y: data.y })}>
```
There's also a related (but different) merged PR that dealt with `react-draggable`'s `transform` creating a containing block that broke `position: fixed` overlays inside the modal [[3]](https://github.com/apache/superset/pull/38274) — it didn't address this resize issue, but illustrates the kind of coordination problems that arise from nesting these two libraries.
This would be a good candidate for a contribution targeting [`Modal.tsx`](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/packages/superset-ui-core/src/components/Modal/Modal.tsx).

@dosu Thanks for the analysis
> A couple of follow-up thoughts:
> 1. Since the default resizableConfig only enables bottom , bottomRight , and right , most users won't hit this bug in practice. Should the fix also tighten the default handles, or is the controlled-mode change alone sufficient?
> 2. You mentioned PR #38274 which dealt with react-draggable 's transform breaking position: fixed overlays. Would the controlled-mode fix here have any interaction with that, or are they fully independent?
> Happy to open a PR for this if a maintainer thinks it's worthwhile.
