This PR hides hover info/diagnostic popovers when code action menu is
shown. We already hide hover info/diagnostic popover on code completion
menu trigger (handled on input).

Note: It is still possible to see hover popover if code completion or
code action menu is already open. This is intended behavior.

- [x] Test hover popover hides when code action is triggered

Release Notes:

- Fixed issue where info and diagnostic hover popovers were still
visible when code action menu is triggered.
