STEPS TO REPRODUCE

0. Use a Wayland Session
1. Have VS Code installed.
2. Start VS Code with the following command-line options "--enable-features=UseOzonePlatform --ozone-platform=wayland" or add them to the .desktop file for VS Code. If you use .desktop logout and login again in your account for KDE to refresh the .desktop entries cache.
3. Have VS Code running in a maximized window in the background
4. Have Firefox running in a maximized window in the foreground. Ensure Firefox shows/uses "wayland" as a window protocol in about:support
5. Have some number of open tabs in Firefox
6. Try to move/change the Firefox tabs order
7. Notice how the VS Code window in the background gets activated on release/end of dragging the Firefox tab

I should add that although VS code is shown to foreground, it does not have focus when this issue happens.
Comment 2 Fushan Wen 2021-06-30 09:04:12 UTC 
I cannot reproduce the issue on openSUSE Tumbleweed 20210628 with Plasma 5.22.2, Firefox 90.0b12 and VSCode 1.57.1
Comment 3 Lyubomir 2021-07-09 11:44:46 UTC 
Hmm, today i experience the reverse - dragging tabs (on mouseup) in VS Code switches the foreground window to Firefox.

We had issues in the past with older firefox that were client issues. 
We haven't seen issues in newer firefox. Please let us know if a problem persists
