Revert "Fix #123327: Crash when operator with properties opens render window"

This reverts commit 5f102ad4.

Apparently this was on the backport list by mistake, a (safer) alternative was commited in 174f8de7

This 5f102ad4 caused #126392 (which is still present in main), we dont want to release 4.2.1 with this though.

Then the current issue only needs to be fixed for 4.3 (main), and we can safely wait for @JulianEisel to be back to do so.
