Thanks applied to master.

I don't think opening a pull request on Github is the right way to
contribute to Qt upstream. They have a Gerrit, and you need to submit
your contribution there, if I remember correctly. Peter Seiderer (in
Cc) can probably help in this process, either by giving you additional
details, or pushing the patch upstream for you perhaps.

Best regards,

Thomas
