Mihai Chira updated FLEX-34344:
-------------------------------
Description:
*Steps to reproduce*:
1. Import and run the attached project.
2. Click on the dropdown and select an item.
3. Right click on the dropdown, which removes it from stage.
4. Press UP/DOWN.
*Actual behaviour*: the dropdown's _proposedSelectedIndex keeps changing,
showing the dropdown is still acting on keyboard events.
*Desired behaviour*: once it's off stage, the dropdown should not react to
keyboard - or any other - events.
*Notes*:
-the same behaviour can be made visible by placing a breakpoint in
DropDownListBase.keyDownHandler after step 3.
-the dropdown stops reacting to keyboard events when it's removed directly, as
opposed to when its parent group is removed.
-I noticed that UIComponent adds event listeners for KEY_DOWN, KEY_UP, FOCUS_IN
and FOCUS_OUT, but never removes them. Is the expectation that components
themselves will remove these listeners when they're off stage, or is it an
omission?
