Is this bug triggering in practice? If not then please say so in the
changelog. If yes then is this patch desired for v3.13 merging and
also please fix the changelog to conform to the standard changelog
style:

- first describe the symptoms of the bug - how does a user notice?

- then describe how the code behaves today and how that is causing
the bug

- and then only describe how it's fixed.

The first item is the most important one - while developers
(naturally) tend to concentrate on the least important point, the last
one.

Thanks,

Ingo
