Kvantum: dark text on dark background tooltips

I'm trying to set up Kvantum together with the KvLibadwaitaDark theme under Gnome, to make my Qt and Gnome apps have a unified look and feel.

KvLibadwaitaDark has tooltips with white text on a dark gray background. This works fine with some apps, like for example kvantummanager:

However, many Qt apps seem to force-set tooltip text colour to black or dark gray. Combined with the dark gray background, this makes tooltips for these apps unreadable. For example wireshark:

The best workaround I could think for this was to create a custom version of KvLibadwaitaDark, that uses black text on a light yellow background for tooltips. Here are my diffs:

This seems to solve the problem:

Is this the best way to do this, though? Or am I missing something? An environment variable I'm not aware of, for instance? I'm mostly a Gnome user and not very familiar with Qt. There are a few Qt apps I use, though, and I really like being able to read my tooltips.

Note that this issue doesn't seem to be specific to KvLibadwaitaDark, as most Kvantum themes seem to use dark backgrounds for tooltips.
