fix: prevent context menu highlight from persisting for touch input

[mgreminger]

When using touch input with the context menu, all of the previously clicked context menu items remain highlighted when the context menu is reopened (see first screen recording below, tested on Chrome and Edge). This change ensures that the most recently clicked item will be returned to the non-active state after the event fires. I think the root cause of the issue is that the pointerenter and pointerleave don't both fire for touch input so the accounting of activeMenuItem is not working the same way as it does for mouse events. I tried setting touch-action: none on the menu items as a alternative solution, but that did not work.

Ah, yes, thank you. I had noticed this and it had slipped my mind... That's the correct fix.
