https://mw-expt-tests.wmflabs.org/diff/dewiki/Ingvar_Carlsson is an example where the image in the figcaption overflows, resulting in a rendering difference. This similar to T171761 but the word-break isn't going to work here

Only thumbnails should get the margin-bottom: 0.5em; from,

Also on https://mw-expt-tests.wmflabs.org/diff/enwiki/Diffusion, it appears that thumb at "Diffusion in the context of different disciplines" is clearing right, when it shouldn't be, since it's floating above the heading. That's a bug in the CSS that needs resolving.
https://mw-expt-tests.wmflabs.org/diff/enwiki/Diffusion shows that TimedMediaHandler isn't recognizing the new output. That should be handled in T272186
From the early results, https://mw-expt-tests.wmflabs.org/diff/enwiki/Anglo-Saxon%20settlement%20of%20Britain is an example of T169975#4176954
We might want to do a round of $wgParserOutputLegacyMediaDOM = true; vs HEAD^ to establish a baseline that nothing is broken.
A round of visual diff'ing is now running with the key "media-test", results at https://mw-expt-tests.wmflabs.org/

From @ssastry on irc,
For where this is used, see for example "Localisation" in the infobox on https://fr.wikipedia.org/wiki/Bratislava

It looks like this is just waiting on QA in T268309 so I'm going to close it but please reopen if that proves problematic.

Also related, T92999
But @Arlolra seems to have found the exception to that rule which we've all forgotten; I await with bated breath.
I think we should file individual tasks for these things so they can be researched more thoroughly.

T258719 is perhaps relevant for which selector to use, but orthogonal to the issue here.
It does use mw-content-$dir elsewhere, but see T258719
Parsoid sets mw-content-$dir based on the page language,

This exists as $wgUseNewMediaStructure now

This was deprecated in https://github.com/wikimedia/mediawiki/commit/8c43d758414925bae6e4442486f3c768102fecd1 as part of T254802

@Arlolra had a more clever idea, which I'll let him relate.

After that's merged, I think this can be closed as a dupe of T162399
Registering a modulestyle with the extension seems like a pretty coarse grained api. The legacy parser only adds the styles/scripts if the tag is used on the page. We currently do that for places where we call the out to the legacy parser, with env->addOutputProperty
Looks like it's happening in https://es.wikipedia.org/w/load.php?lang=es&modules=mediawiki.page.gallery&only=scripts&raw=1&skin=vector&debug=true
The legacy output has the same dimensions height="120" as Parsoid,

In https://github.com/wikimedia/mediawiki/commit/16b76a486d774e31283a62c0a17cfc9f356ca106 we changed the figcaption from display: table-caption; to display: block; since the figcaption wasn't always present and we didn't want the bottom border to depend on it.

See T267282#6641741 where we're saying this is valid in the case where |link=| suppresses the anchor element around the image.
