I want to restore part of an old version on Commons. Usually on wikipedia I can just go to the plain text of past versions. Example https://en.wikipedia.org/w/index.php?title=Andrew_Goatly&oldid=744109408
However when I go to a past version on Commons and I click edit, I do not get the past version. I get a comparison of edits, with the text restore. Example https://commons.wikimedia.org/w/index.php?title=File:Megacriodes_saundersii.png&action=mcrrestore&restore=152390387
How can I get the old text? So some past changes were bad. But alot of good has been done afterwards. How can I partially restore the good edits?
If this is a bug, please fix it, because it removes a vital part of editing, namely the actual text.
