DO NOT MERGE: Revert "Check display id of the last hover window before it is cleared"

This reverts commit ff0c66e855925476c5ce06ad133f9084e725f96a.

Reason for revert: b/263272128

This platform change causes a regression in CTS tests. Since the CTS test fix will only be released in the next quarterly release, we must wait for the test to be released before landing this fix.
