Wrong conclusion.

The fact that QTextBrowser hasn't changed does not mean the help display
is the same as before.

Maybe the set of CSS features the help style uses changed?

Oh wait. It has. Even a couple of time since "long ago".

Last time on 2015-10-16, with the commit message mentioning "including
simplified CSS rules suitable for rendering with a QTextBrowser".
