tmtron opened a new issue #10675: Brush drag gets stuck when the mouse leaves the chart area
URL: https://github.com/apache/incubator-echarts/issues/10675
 
 
   ### Version
   4.2.1
   
   ### Reproduction link
   [https://jsfiddle.net/tmtron/kdaqhpjv/92/](https://jsfiddle.net/tmtron/kdaqhpjv/92/)
   
   ### Steps to reproduce
   * left-click in the chart area and HOLD the left button
   * now the brush-drag is active: we can move the mouse around and the area will follow
   * but when we exit the chart area (e.g. far to the right on the grey area) and then release the mouse button (still on the grey area), the brush-drag mode gets stuck
     * what I mean is, when you now move the mouse back to the chart area, the brush-drag is still active: i.e. the mouse move will resize the brush area although the left-mouse button is NOT pressed down anymore
     * this will only stop when you make another click inside the chart area

   ### What is expected?
   the brush mode should stop (same as releasing the pressed mouse button)
   
   ### What is actually happening?
   the brush mode ist stuck: when you release the mouse button outside the canvas, and reenter, the brush is still following the mouse movements
   
   As a workaround I tried to fire a 'mouseup' event when the 'globalout' event occurs, but that does not work.
