quill-delta[html] fails to build when trying to include older lxm and cssutils versions

Installing current lxml (lxml-5.3) and cssutils (2.11.1) go well, but quill-delta[html] requires lxml<5.0,>=4.3 (lxml-4.9.4) which fails to build and cssutils<2.0,>=1.0 which does not exist anymore.

I tried a local install with current lxml and cssutils and it works for my needs.

Any plan tu upgrade these dependencies ?

Thanks !
