This report is related to the experimental --preparser-scope-analysis flag which we don't ship. The flag is generally not working yet (as in, JavaScript won't run).

Is it OK to lower the priority and remove releaseblock-beta?

Actually, removing bug-security too since this is not a security risk atm.
