Combobox Does Not Collapse When Clicked

[hawkticehurst]

Describe the bug

Not completely sure if this should be categorized as a bug or not, but the default behavior shipped by the FAST Combobox is that a user can click the topbar element to expand it but cannot click the topbar element to collapse it. The only way to collapse a Combobox is to click outside of its bounding area.

FAST Example
Toolkit Example

This runs in contrast to the Dropdown (FAST Select) which can be expanded and collapsed by clicking the topbar element.

To reproduce

Steps to reproduce the behavior:

1. Create a vscode-combobox
2. Click the element to open
3. Try to click the element again (it will not collapse)

Expected behavior

My expectation is that the behaviors of the Combobox and Dropdown should be aligned. Or at the very minimum clicking the Combobox chevron should collapse the Combobox.

Additional context

@daviddossett Your feedback on this would be helpful because I'm not sure what the common behaviors for a Combobox are (i.e. maybe this is a common UX convention for Comboboxes?).

Great catch!

Closing since comboboxes have been removed from the toolkit.
