Tall Tiling is not working correctly on one particular workspace

[llimllib]

Describe the bug

Tall tiling on my main (external) monitor is not working properly. Here it is showing windows in four quarters instead of main on the left and three on the right:

If I create additional windows, they get added correctly to the right column, but the left column always has two windows instead of one.

In posting this message, I discovered that it only happens on this particular workspace! It has been persistent for about a week now, even through reboots, but it doesn't happen on additional workspaces.

I just closed that workspace, and can no longer reproduce the problem. I'm reporting it anyway, because it frustrated the heck out of me and clearly there's an issue somewhere!

Applications:

I'm using firefox and iterm to demonstrate the problem, but it happened with any app on that particular workspace.

To Reproduce
Steps to reproduce the behavior: I can not reproduce it now that I have closed that workspace

Expected behavior
tall layout behaves as advertised, which it does on all other workspaces

Versions:

• macOS: 12.3.1
• Amethyst: 0.15.6

Debug Info
I took this debug snapshot while the workspace was open:

Additional context

Sorry to post an issue I can't reproduce any longer! No idea how I got that one particular workspace wedged such that it even persisted across reboots
