Review Comment:
The construct looks more like the normal `null`-Check idiom, for `Optional`, I would use:
```suggestion
return references.getOffsetRange(element).orElse(OffsetRange.NONE);
```

Review Comment:
This method is called often, we should cache the child items.

Review Comment:
I noticed, that double clicks in navigator always jumped to the first element in the block, not the right one. Turns out this typo is responsible.
```suggestion
addReference(attr, actx);
```
