LGTM. Thanks for fixing it.

I wasn't aware that csproj property existed. The only concern I have is if we are making the CI slower now that all test methods from this project will be executed individual instead of parallel. I'd be more inclined on making individual test methods not run in parallel, instead of the whole project. Thoughts?

Same here, I found it by accident when I was refactoring the code for #62132

I was also concerned about the execution time. Before my change it was taking 0.138s to run the tests on my machine, now it takes0.184s so I think that we are fine. An advantage of having it per entire project is minimizing the risk of adding a new test in the future and forgetting about annotating it.

Ci failure is known and unrelated (#62028):
