Ability to view edit history.

[ara4n]

Is your feature request related to a problem? Please describe.

Many apps (Element Web, classic Element iOS/Android, Threema, Signal, even iMessage) let you view the edit history of a given message. This is particularly important for dealing with bad-faith edits (i.e. where someone edited a prior msg to change the meaning of the subsequent conversation).

Describe the solution you'd like

Show the diffs of history of messages in the context menu when you long-tap on an edited message.

Describe alternatives you've considered

iMessage's UI is quite cute, in that it pops open a thread to show you the history inlined int he timeline. But it's overkill imo; would be good enough just to show the history in the context menu.

Additional context

It's frustrating from a competitor-parity perspective that the others have this, and we used to, but we don't any more.

I'm really missing this these days (eg i have a confusing message from someone which appears to have a double negative in it - but it's been edited. did they deliberately add the double negative, or did they fix some other typo in the msg? They're not answering me any more, so either i need to spelunk as a dev in View Source, or find a different app to find out...)
