Please branch and build litehtml in epel9. If you do not wish to maintain litehtml in epel9, or do not think you will be able to do this in a timely manner, I would be happy to be a co-maintainer of the package.
I have tested and the rawhide package builds in EPEL9, but first gumbo-parser has to be added to epel9. I have requested gumbo-parser for epel9 in this other bugzilla. https://bugzilla.redhat.com/show_bug.cgi?id=2037090
I've created the branch and added you as collaborator on the epel9 branch. I've also done the initial import, but as you noted, gumbo-parser is missing. I'd apprechiate if you could maintain the package for epel9, as I don't use EL.
