LGTM, and I could also test it to see that it works!

Thanks! I asked the user that reported this, to test as well, so I will wait a bit more before merging.

Merging. @raulillo82 added 15.4 first, 15.5 later and didn't have conflicts. It's the opposite of what the user at the ML did (15.5 first, 15.4 later), so FMPOV the test is valid.
