Following T117279 some changes were made to #MobileFrontend (Special:MobileDiff) and Mediawiki core. However it introduced some regressions. I have found these two bugs for now. I suspect there could be other bugs.
== 1. Mark as patrolled link isn't being shown in this new Special:MobileDiff
=== Steps to Reproduce:
* Go to a wiki where patrolling is enabled
* Find an unpatrolled edit, you must also have `patrol` right to be able to see the mark as patrolled button
* View and compare its diff in both mobile and desktop mode
=== Actual Results:
* A "mark as patrolled" button used to appear below the mobile version of an unpatrolled diff. This button in mobilediff is hidden but it is still intact in the desktop diff.
=== Expected Results:
* Mark as patrolled button is displayed
== 2. Buttons to switch to a VisualDiff doesn't work
===Steps to Reproduce:
* Enable VisualDiff beta feature.
* View a mobilediff
* You'll see two grouped buttons. One enabled and one disabled.
* Click on the enabled button since you can not click on the disabled button

=== Actual Results:
* Nothing happens! You can not switch to a VisualDiff! It seems the JS code to load a visual diff isn't being loaded.
=== Expected Results:
* Visual diff works as usual like in the desktop version.
== 3. Mobile diff width is broken
=== Steps to reproduce
* Visit [[https://commons.m.wikimedia.org/wiki/Special:MobileDiff/386306397]] from a mobile device or resize your screen. The width is broken.
