Android Tor Browser 60esr-based doesn't work on Android 10 (Q)

I don't know why yet. I saw a few reports of this not working, but alpha (esr68-based) is working. I'm guessing Mozilla fixed something for this. On an emulator, I don't see any error messages in the logcat output, but browser content is not rendered (resulting in a white page, both privileged and web content), and all settings are disabled. The latter issue is usually the result of libxul not loading (therefore Gecko is not available), however the logs show Gecko is initialized and the javascript runtime is working.
