I tried running this test on Windows and the test passes without any changes. I saw in the bug that this is intermittent. How does this change to `BasicPopupMenuUI` fix the root cause of the intermittent issue?

Looks like the change is also in any instance where the action is on a non-JMenu object, which means this change might possibly affect other UI components as well other than what we expect for this intermittent failure.

Also a side-note, this test fails for me on macOS when the problemlist is for `linux-all`. And the de-problemlisting of this test may not be needed. This issue is for the windows failure it seems. There's a separate issue for the intermittent linux failure [JDK-8321303](https://bugs.openjdk.org/browse/JDK-8321303).
