Something weird happens when you repro this, then open settings and try to click outside of the settings modal to close it. Noticed when I copied the app version from settings.

Error log I am seeing on develop for this

This might actually be 2 issues:

1. element should not fail and just close the modal, but instead at least say how/why it fails
2. the message may or may not be to spec, as the author says

   I did one edit in Fluffychat, one in Element-desktop and one in Element-android, I think. Testing, I call it. :-)

I should note that I can view the diffs of other edited messages

All I can add is, it gets pretty tedious to see markdown rendered differently on different platforms, and then for various editors to mangle it when round-trip editing a message. Rather than hunting down specific edge cases, which could be an endless rabbit-hole, I would prefer this class of bugs to be addressed by any moves possible toward standardising markdown across platforms, even if that means choosing a markdown flavour that is better standardized over one that includes a cool feature.

@julianfoad That would be a different issue (https://github.com/vector-im/element-meta/issues/1493 perhaps), as this one is just about the edit history dialog crashing.
