Tooltips intermittently fail to disappear on mouse out

Summary

Tooltips intermittently remain visible permanently after moving the mouse out of the parent element, requiring a page refresh to clear them.

Steps to Reproduce

1. Navigate to any page with tooltips in GitLab v18.3
2. Hover over an element that displays a tooltip
3. Wait for the tooltip to appear
4. Move the mouse cursor away from the parent element
5. Observe that the tooltip sometimes remains visible

Expected Behavior

Tooltips should disappear immediately when the mouse cursor moves out of the parent element that triggered the tooltip.

Actual Behavior

Tooltips intermittently remain stuck on screen permanently after moving the mouse away from the parent element. The tooltips do not disappear and remain visible until the page is refreshed.
