Add linebreaks to a caption in wikitext doesn't generate <p> tags, so adding <p> tags shouldn't generate linebreaks.
Currently
...<figcaption><p>FOO</p></figcaption>... -> [[File:Foo.jpg|\nFOO\n]] ->
whereas
[[File:Foo.jpg|\nFOO\n]] -> ...<figcaption>\nFOO\n</figcaption>...
Should be
...<figcaption><p>FOO</p></figcaption>... -> [[File:Foo.jpg|FOO]] ->
The HTML above is generated if the user adds content to an empty caption in VE.
What happens if there are multiple paragraph tags? What is the editor intention there? @Sbailey and I were discussing this and we are going to just run them together with a single space.
This is ignoring the broader discussion we were having today about loosening some restrictions -- that is a different thread to be picked up later.

[mediawiki/services/parsoid@master] Image captions ignore paragraph tags
That's fine with us. We're doing our best to prevent users from inputting more than one line at the moment.
Ed, Subbu and I have discussed that for multiple p tags in the caption, we will be replacing the new lines with a single space, merging the captions together. The hope is that the captions would be sentences and that joining them with a space will be a reasonable way to "fix" this situation.

[mediawiki/services/parsoid@master] html2wt: Image captions ignore paragraph tags
The main part of this ticket, as it affects VE, is done now and will be deployed when we push out code next. So, if there is a single p-tag, we handle that properly.
Se could also handle the case more generally to also suppress newlines when there are multiple p-tags. That work is yet to be done. But it is lower priority since VE doesn't introduce multiple p-tags during editing sessions.
