XML roundtrip failing on &

[ybasket]

The roundtrip tests in http4s-fs2-data are flaky, they sometimes fail on escaped entities:
https://github.com/http4s/http4s-fs2-data/actions/runs/5514890884/job/14930647806?pr=97 (only &)
and https://github.com/http4s/http4s-fs2-data/actions/runs/5481925805/job/14845710701 (combined with a lt).

It's not yet clear whether the input is actually invalid XML or fs2-data handles it incorrectly, to be investigated.

Failing data from above are:

and

This problem seems to come from the way scala xml serializes the nodes. Do you confirm @ybasket?
