Where is the determination to bail out made based on _provider?

Throughout the file. All places that use _provider are already doing a null check.

The current `FindWindowOfActiveTSF` implementation can result in infinite recursion which we must guard again. This change is not tested as I don't know how to trigger the issue to begin with (a missing CoreInput thread). (cherry picked from commit 9243104) Service-Card-Id: PVTI_lADOAF3p4s4AmhmszgVIDM8 Service-Version: 1.21
