This is broken in 2.9.12+dfsg-3 on impish.
It is not broken in 2.9.10+dfsg-6.3ubuntu0.1 on hirsute.
There are some fixes in master since the 2.9.12 release was cut.

I'm planning to pick all 3 of the following commits from upstream
master since they are all intertwined. With this patches the
regression is fixed.
85b1792e37b131e7a51af98a37f92472e8de5f3f:
Work around lxml API abuse. Make xmlNodeDumpOutput and
htmlNodeDumpFormatOutput work with corrupted parent pointers.
13ad8736d294536da4cbcd70a96b0a2fbf47070c:
Add patch from upstream to fix regression in xmlNodeDumpOutputInternal.
Commit 85b1792e could cause additional whitespace if xmlNodeDump was called
with a non-zero starting level.
92d9ab4c28842a09ca2b76d3ff2f933e01b6cd6f:
Add patch from upstream to fix whitespace when serializing empty HTML
documents.
