The post revision dialog is broken on very long posts. aschrijver reported an issue on a post with 110kb of content, where the revision dialog remains blank and shows NaN as the revision number after the 36th revision. This occurs despite successful saving after increasing the character limit. codinghorror acknowledged the problem, stating that shipping all revisions to the client causes issues, which joffreyjaffeux is working on. Other users, B-iggy and darkpixlz, have encountered similar issues on their forums, with darkpixlz being asked to check for errors in the /logs to help resolve the problem.

Save was successful, but when trying to check in the Revision dialog to see the diff, this dialog remains blank and also the revision number is shown as NaN:
It is not a loading issue, dialog html remains blank no matter how long I wait. This happens using Firefox 84 on Ubuntu, and the installed forum software is at version 2.7.0.beta7.
