This seems to still be occurring: https://es.wiktionary.org/?diff=5009104

Hmm,

> echo -e ": test '''<nowiki>\n123</nowiki>''' asdf" > t
> git co 925136a
> cat t | php bin/parse.php --wt2wt
:test '''<nowiki> 123</nowiki>''' asdf
> git co master
> cat t | php bin/parse.php --wt2wt
:test '''<nowiki>
123</nowiki>''' asdf

However, continuing,

> cat t | php bin/parse.php > t.html
> sed 's/asdf/asdfe/' < t.html > t2.html
> cat t2.html | php bin/parse.php --selser --oldtextfile t --oldhtmlfile t.html
: test '''<nowiki> 123</nowiki>''' asdfe

But note that if we started with : test <nowiki>\n123</nowiki> asdf, it would have been fine. The patch does account for some cases of selser reuse.

This is the limitation of https://github.com/wikimedia/parsoid/blob/master/src/Html2Wt/WikitextSerializer.php#L1172-L1185

The nowiki is nested in the idiomatic text element, which doesn't suppress the single line context.

Presumably this isn't too common since it's true of all the other cases there, not just nowikis.

Also, I'm sure it's discussed elsewhere, but it would really help to not be normalizing the entire list when an item is added.
