[IntelliJ] IDEA 2025.2 does not start without internet connectivity

Start of IDEA 2025.2 gets stuck (at showing the splash screen) when there is no internet connectivity (connected only to an internal network). This is the relevant part of the output from jstack in the thread DefaultDispatcher-worker-3 - apparently there is a HTTPS call being made without the appropriate timeout:

I have reported this issue at https://youtrack.jetbrains.com/issue/IJPL-202443/IDEA-2025.2-does-not-start-without-internet-connectivity before I have found this GitHub repository.

Start at AzureActionsListener.appFrameCreated and follow the initialization path through AppInsightsClient, ExperimentationClient, and ExperimentationService.updateFeatures. Reproduce startup with only an internal network and inspect the HTTPS call shown in the jstack output. Done means IDEA reaches the usable interface without internet connectivity instead of remaining on the splash screen.
