[NTUSER][USER32] Workaround tracking menu on CORE-17338 (#4048)

This prevents the tracking menu from erroneously closing itself right after it was opened in some cases.
    Fixes CORE-17338 which got unhidden by 0.4.15-dev-1126-g 58b0558f94abee52ce1c261063d4f4b884e96310
    And fixes CORE-15760 which got unhidden by SVN r74972 == git 19dd22d42218da03ab748879aa3c3e288f41697e

Since both symptoms look very similar but the unhiding revisions did differ,
    that could mean we do have some kind of race condition here.
    I guess this fix is more like a workaround. I do intend to port it back nevertheless.
