Repro steps

  1. 1.Click 'Box Select' in the chart toolbox in the top right corner
  2. 2.Drag across the chart area to create a brush selection box over data bars
  3. 3.Click 'Clear Selections' in the toolbox to clear the active selection

Expected

Clicking 'Clear Selections' clears the chart selection box and returns the toolbox button to its default unselected state (or momentarily triggers an action without remaining active).

Actual

The brush selection is removed from the chart, but the 'Clear Selections' toolbox icon stays highlighted in an active/selected state when no selection exists.

Evidence

visualAt 19.0s, the box brush selection highlights bars Apr through Oct and dims unselected bars.
visualAt 25.0s, after clicking 'Clear Selections' at 24.4s, all bars return to normal opacity but the 'Clear Selections' button in the toolbox remains highlighted.
