This is likely a bug, unfortunately. All I can recommend is writing into Special:Contact/bug with details of where the problem can be found and how to reproduce it.

Even if reproducing it seems really obvious it's a good idea to explain it as much as you can to make the lives of the staff, who need to be able to reproduce it before filing a bug ticket internally, and the developers, who fix it, easier and hopefully leading to a quicker fix.
