Markdown titles in docstrings not rendering properly in published docs pages #477

It seems the markdown (sub)titles used in the docstrings no longer render properly since #445. They now just show as plain text. The default Documenter.jl theme also didn't do much with these, but at least it rendered markdown titles in bold face, which was usually enough to indicate some structure in the docstrings.

It would be nice if this could be restored using the new DocumenterVitePress rendering.

[EDIT] Aparently this issue is only present on Linux (confirmed on Ubuntu and Mint), while things render fine on MacOS or Windows.
