- Change ASSR enabling code while preserving original code flow as much as possible
- Simplify the code on guarding with internal display flag

This is a backport of this patch to 5.13. I originally sent this out as a follow up to the reply that the original patch failed to apply to 5.13, but it hasn't been applied yet. Resending to make sure it didn't get lost.
Not lost, just not caught up on yet. Now queued up, thanks.
