Do you mean such overlay, as displayed in gitpod enviroment ?

@grzanka Yes. If there are any errors, even unrelated, the tests will fail because the overlay blocks Selenium from interacting with the application.

What do you think about investigating why the overlay appears at all and modify the code to fix it (to make overlay gone), not the tests ?
It seems like source of some kind of errors/problems.

@grzanka Yes, there probably shouldn't be errors to begin with and the source should be investigated. However, the failing tests cause issues when working on unrelated things. I made this change in order to run tests locally for the mui bump, I wouldn't be able to finish it otherwise.
This change might not be that necessary, I can close this issue if you think so.

Can you invest 15 min on checking what can be the source of the error ?

Is it some asynchronous code executed without a catch ?

@grzanka Sure, I'll take a look at it.

Does this problem appear with vite as well ?

#1696

It should disappear with vite.

note: I've managed to narrow the error down to this commit: 16153ed
I wasn't able to find out what's causing it just yet
