Why GridListItem is selected onPressStart?

[QzCurious]

In short, I'd like to ask a way to make GridListItem be selected onPress, to make the UI behavior more aligned.

This is how GridListItem currently working, the selecting behavior is not aligned:

In addition, ListBoxItem behave the same way:

The Decision on useGridListItem (useSelectableItem)

For onPressStart, I find this requirement :

onPress requires a pointer down event on the same element as pointer up. For menus,
we want to be able to have the pointer down on the trigger that opens the menu and
the pointer up on the menu item rather than requiring a separate press.

Pretty love how I can hold then up to select an item in the menu. But I thought that the requirement is a solved problem by MenuTrigger and SubmenuTrigger, right? Why it's a concern in scope of useSelectableItem?
