Thunderbird Check spelling popup window is now default upper left corner.
In a recent version change of Thunderbird, the Check spelling popup window that occurs when send is selected, used to remember the users location on the desktop. Now it defaults to upper left corner of the screen. In my case I compose new email on the right side of my desktop. I can move it. But the next email it returns to the upper left corner again. This used to work correctly.

Tested this on Windows 10 OS I have two version running symultaneously - version 68.12.1 and 78.9.0
68.12.1 if I move from top left to top right, close and reopen, it remembers the location. 78.9.0 if I move from top left to top right, close and reopen, it does not remembers the location and keeps opening on top left.
So this is reproducable and not just something on your computer.
Also tested the opening of the 'Write' window in preferred location and this is remembered on both versions, so that is working as expected.
Checked for reported bugs and located one very old and one more recent. https://bugzilla.mozilla.org/show_bug.cgi?id=1652290 https://bugzilla.mozilla.org/show_bug.cgi?id=531833
