Manage revisions page: Bad link and styling

If you open revisions of any page, and click on “Manage” button (screen: https://screens.zvladnu.cz/1/chrome_2023-03-07_02-07-56.png), you get to page with URL like this:

/wp-admin/admin.php?page=rvy-revisions&revision=26483&action=view&nc=107a3be8

The page is not styled correctly, see screen: https://screens.zvladnu.cz/1/chrome_2023-03-07_02-10-04.png

Is it possible to fix it, please?
