Subject: SuperCollider's Help Browser doesn't display text (possible
 QtWebEngine issue?)

Hi!

I've noticed that when starting SuperCollider IDE (with the scide
command) the Help Browser (which is the panel on top on the right side
with vanilla/no configuration) doesn't show any text.  IIRC
SuperCollider's documentation is HTML documents (you can also browse it
online [1]) displayed through some QtWeb-widget (I am no expert in Qt).

My first question: is this reproducible?  Or do others also see no text
in the Help Browser?


I have tried adding qtwebengine as an input and passing a configure
flag, but this didn't change the issue:

I'm more than happy to hunt that bug down but am grateful for any
pointers to where the issue could possibly originate.
