EditorUtility DisplayProgressBar only shows up for one frame and then it is invisible / not showing anything anymore



How to reproduce:
1. Open attached project "" and scene "SampleScene"
2. Enter Play mode
3. Observe the new progress bar window

Expected result: the progress bar stays for as long as the Play mode is active
Actual result: the progress bar shows up for one frame and then disappears. Switching the Editor onto other monitors and maximizing/windowing the Editor results in the progress bar window being showed for one frame

Reproducible with: 2020.1.0a23, 2020.1.0f1, 2020.2.0a18
Not reproducible with: 2018.4.25f1, 2019.4.6f1, 2020.1.0a22

This was not reproducible on MacOS with 2020.2.0a19

    Resolution Note (2020.2.X):

    Kinda wrong usage of DisplayProgressBar API. Will clarify in the docs.

    I need to block the editor for some process. "Progress" api is not good for this and EditorUtility.DisplayProgressBar is never showing anything. How can I handle this?
