[BUG] Tooltips are drawn behind main window

[grappigegovert]

Describe the bug
The tooltip that appears when you hover over a result in the deep search tab anything in the left pane gets drawn behind the main window, and even behind other applications.
edit: It looks like this holds for any tooltip.

To Reproduce
Steps to reproduce the behavior:

1. Use Deep search to search for something with a long name/value
2. Resize the RPKG window so that the name/value would extend beyond its bounds
3. Hover your cursor over it

Expected behavior
The tooltip is drawn above everything else.

Screenshots

RPKG tool version: [e.g. 2.14]
I've tested it on 2.25.0 and 2.33.0 and got the same results

Quick addition:
It seems that everything works as intended as long as the RPKG window does not lose focus at any point.
As soon as you focus another application once, any subsequent tooltips will be drawn behind rpkg tool and also behind that application.
