Edits sometimes show original msg, not edited msg.

[ara4n]

Steps to reproduce

1. Send a message on another client (EW in this case)
2. Someone reacts to it (this may or may not be important)
3. Edit your msg
4. More reactions happen

Later, view the msg in scrollback on EX. It’s shown as edited, but the contents shows the pre-edited contents, not the edited content! 🙀

concretely:

is a msg i sent, and then fixed the thinko of “go” to “typescript”. but the edit doesn’t show up.

Outcome

What did you expect?

reliable edits

What happened instead?

flakey timeline code.

rageshake is down so i can't submit logs. https://matrix.to/#/!IIDRCwzJTNnOmMxacp%3Amatrix.org/%24BkoaVoIn-FFKS64JNoVQUiJuF7e_IG0J1wB-Z41A7BQ is the msg in q

[ara4n]

it often seems to flip back and forth - i just saw it flap between the edited and non edited version in the timeline about 3 times after having sent the edit...

Still 100% reproducible (reactions don't matter). They fix themselves after re-entering the room after having loaded them once and then break again when clearing out the cache.

Already reported on the RustSDK under matrix-org/matrix-rust-sdk#3492

@Hywan could this be fixed by the event cache storage?

I've closed the SDK issue, because lots of engineering work has been spent on this, and most issues should now be fixed. As explained there, please open new issues if that happens again, with precise STRs; the symptom (missing edit) can be caused by many causes; for instance, there are some rageshakes here that relate to local echoes for edits, unrelated to the original issue filed here. Thanks!

thanks @bnjbvr for all the fixes. Let's close this issue and create more accurate ones if needed.
