Any input on how to debug?
Did you enable "Visual differences" on https://de.wikipedia.org/wiki/Spezial:Einstellungen?uselang=en#mw-prefsection-betafeatures ?
Did you try to reproduce on https://de.wikipedia.org/w/index.php?title=Panguana&type=revision&diff=178094775&oldid=172633804&diffmode=source&uselang=en ?
Or somewhere else?
For the records, it works for me now on the second link.

Hi Nithin1999 and thanks for your patch!
Unfortunately this patch is for the wrong code repository. RevisionSlider is a separate extension. Its code does not live in the "mediawiki/core" repository. You need to provide a new patch against the correct repository; that's why I'm abandoning this patch here as it cannot be merged.
For any future patches, please follow https://www.mediawiki.org/wiki/Gerrit/Commit_message_guidelines and add a meaningful commit message.
Resetting assignee as Nithin has not been active in the last days. Note that anyone (including Nithin, of course) is free and very welcome to work on this and improve Nithin's patch in Gerrit. Thanks :)
