Broken edit history under certain circumstances

If a topic has two edits, of which one is just tag additions, the latter edit doesn’t show up.
You can find an example of this here


hitting the arrow leads to this

might be a server error

I actually can’t use the arrows at all so idk, maybe your browser doing funny things?

now that i’ve checked it it only has one edit now?

update: it now breaks if there’s only one edit and it’s also a tag edit
