This reverts commit ab51a026 and fixes the test that broke the first time it landed.

This reverts commit 885b2f56 to green up the build.

Submitting on red to fix the build.

In the process of fixing #90044, I realized that it's also possible for hovered tooltips to show more than one at a time if the widgets are nested, so this PR is a fix that prevents more than one tooltip from showing at a time with hovered tooltips.
