I see that there have been a couple of reverts in this part of the codebase. We'll have the people involved in them take a look.

Thank you very much.

Thanks for the report. Note that the above commit (2749d03) didn't rectify the problem - it was a revert of the fix, which had been applied too late in the release cycle (during a code freeze).

It was due to be re-applied in time for 5.26.1, but somehow fell between the cracks. Apologies for that, but it has since been re-applied to blead (the latest development branch, working towards 5.28.0) in commit 488307f and should appear soonest in 5.26.2.
