Dear Maintainer,

I'm workign on trimming the key package set.

https://release.debian.org/key-packages.html

qt6-webengine is a key package an thus also
pulling html5lib in the key package set.


The build of qt6-webengine checks for html5lib
and then _seems_ to never actually use it for nothing.


Could this check & python3-html5lib be dropped ?

Please see with upstream wether this is just a leftover
of former html5lib usage.

Greetings

Alexandre
