your response was very insightful, thanks! It turns out that the solution
doesn't quite work, as the '<p>{.quotelead}' gets converted to HTML as
'<p>{.quotelead}', which doesn't match. So I removed the '<p>' part in the
replace statement (line 194), which now reads

ret = html.replace('{.quotelead}', '<p class="quotelead">')

For completion, here is the patch that resulves the issue. If nobody complains,
I'll open an issue in the gilab to fix the bug.

thanks!
