Text Cursor Position Loss after ALT+TAB Context Switch on WSL2

I first noticed the issue I describe below when using QOwNotes (built from source), but it may be widespread: the same issue appears in Qt Creator; and the "orderform" example from the relevant Ubuntu APT packages (`qtcreator` and `qt6-base-examples`). I am working within Ubuntu 24.10 under WSL2 on Windows 11. I'll describe the issue in the simplest of those 3 applications: the "orderform" Qt example. It can be launched using:

/usr/lib/x86_64-linux-gnu/qt6/examples/widgets/richtext/orderform/orderform

I start by editing some of the text in the main "orderform" window, and switch to another window via ALT+TAB, or by clicking the taskbar icon with the mouse. When I then switch back, the program has lost track of my previous cursor position (or pane/subwindow in general). I would expect that typing on the keyboard will continue editing the "orderform" text where I left it. Instead I have to use the mouse, and click in the pane/subwindow (and try to remember where/what I was last writing).

I wondered if all Ubuntu GUI applications under WSL were affected. I tried Evince (installed via APT as in `sudo apt-get install evince`, and identified that Evince does not have this issue. For example, one can open a pdf with Evince, and click the top left button to show the side pane. By clicking in the side pane one can press UP/DOWN to move from page to page. The side pane is still active after a pair of ALT+TAB keypresses. Clicking instead in Evince's main pdf view, lets UP/DOWN now traverse the pdf with finer granularity (almost line-by-line); and a pair of ALT+TAB keypresses causes no problem here either.
