[Combobox] While focusing on Chip's close button, spacebar opens Combobox menu

[macandcheese]

Actual Behavior

When using Combobox, and focus is on a select item's representative chip's close button - using Space key will open the Combobox item dropdown.

Expected Behavior

I'd expect the Space key to close the chip (match Enter), as the Chip component in isolation does.
