[ci] Fix Playwright test times out/fails because target closed

[ilonatommy]

Fixes #99961, #100307.

1. I made a mistake in the last fix - we changed OnInitialized to OnAfterRender but we kept OnPageLoaded to trigger the test, instead of waiting for OnAfterRender to finish to make sure all buttons are loaded. Most of the times it worked fine but it was not reliable.
2. We were entering OnAfterRender multiple times and triggering the event chain even more than 10 times in one test, some of these connections already finished and closed the app, the others were in process and failed with error. Now we make sure we trigger it only once.

Blocker:

The test occasionally times out. The last log is [info] Debugging hotkey: Shift+Alt+D (when application has focus) and OnAfterRender is never triggered. In debug runtime the problem is hit in each run:

It does not fail anymore with the error from the original issues. Failure is not connected.
