[Interest] Backporting bugs to Qt 5.6

[Danny Smit]

Hi all,

I'm running into two (old) Qt bugs using the latest Debian, with still
uses the LTS Qt 5.6. Preferably I'd like to see them fixed upstream,
so that the whole world can benefit from the changes, instead of
applying patches locally. I'm willing to send pull requests of needed.

My real question is, do I need to send pull requests in order to get
bugfixes backported to the LTS versions? And is likely that my request
for such backports will even get accepted?

It currently concerns the following two issues:
https://bugreports.qt.io/browse/QTBUG-37641 (not yet fixed, but fix is
described in issue)
https://bugreports.qt.io/browse/QTBUG-48344 (fixed in Qt 5.11)
