TargetCamera mangles ui when an unusual ritual is performed.

[coolcatcoder]

Bevy version

0.15.2

What you did

I create 2 windows. I create some ui that targets the 1st window. I get rid of the 1st window. I switch the target of the ui to the 2nd window.
Minimum viable problem: https://github.com/coolcatcoder/bevy_ui_problem

What went wrong

For some reason, the ui gets horribly mangled. This does not happen if I despawn the 1st window after I switch the target.

I think this might already be fixed in main or in one of my PRs waiting for review. #17579 should work.

I tried to construct an example like you described but I couldn't replicate the issue, so if you could post a minimal example that would be a big help.

I'm trying to construct a minimal example, and it should be done at latest 12 hours after this message is sent. (It would be done sooner, but I'm not available for the majority of today, unfortunately.)

Here is the minimal example: https://github.com/coolcatcoder/bevy_ui_problem
After you run the code, you just close the window with the ui on it, and it will switch to the other window, and get mangled.

Just tested it on the main branch of bevy, and it works as it should, so this problem is already solved!
