I agree with the patch, the patch restore the code how it used to use the same getAllPermissions fn after throwing a deprecation message here I tested on my local and working fine for me. Hence merging.

Opps this should have gone agains the rc - people hit this as a regression in 5.44 - but it is in 5.45 (would have hit 5.44 if it had been agains the rc)
