[Bug] Drag and droping outside of sidebar not working when maximised

[leoniro]

Abstract

Dragging tabs and dropping them outside of the sidebar does not detach the tab into a new window when Firefox is maximised. With a non-maximised window, it works as expected with the default "Drag and Drop" setting, and the tab goes to a new window.

Steps to reproduce

1. Start Firefox with clean profile.
2. Install TST.
3. Open a few new tabs and maximise Firefox.
4. Drag a tab and drop it outside the sidebar.

Expected result

Dragged tab should be detached into a new window.

Actual result

Nothing happens.

Environment

• Platform (OS): Windows 10 Pro 22H2
• Version of Firefox: 124.0.2 (64-bit)
• Version (or revision) of Tree Style Tab: 4.0.13

I only reproduced this with a fresh Firefox install on Windows, but I have the same issue on my Ubuntu work laptop, with a small difference: detaching still doesn't work when Firefox is maximised, but works only ocasionally when non-maximised.

Oh, I just realized this exact issue has been discussed in #3523 and that you already commited a fix a couple hours ago. Sorry, and thank you!
