Question ALT + Printscreen not working in OnScreen Keyboard

[mmp09]

Hi,
I have a PC with Windows 11 Pro 22H2. I also have a laptop with Windows 10 64.
I just noticed that when I start OnScreen Keyboard and press ALT + PrintScreen, then it does not capture the current active window screenshot, incidentally the same on screen keyboard screen.

ALT + PrintScreen is working fine on the actual keyboard, but this combination does not work in OnScreen Keyboard.
The same onscreen keyboard does capture entire screen when I just press PrntScn in it.

I am not too sure if this is behavior by design or there's something to look into? Also it's observed in both Windows 11 as well as 10
Internet search did not reveal anything.
Any suggestions shall be great to know.
Thanks.

I guess my understanding was not correct in the first place. The onscreen keyboard ALT + Print Screen does not capture itself as active window, it captures the active window which is running behind it.

And I had no active windows open. So it was not capturing anything.
After I opened a windows and pressed ALT + PrtnSc, it worked!!
