Lost edit after going offline and coming back online

[PVince81]

To Reproduce
Steps to reproduce the behavior:

1. Open the text editor
2. Type some text "first line"
3. Wait for save
4. Type some text "second line" and quickly disable the laptop's wifi before it saves.
5. Wait for about a minute
6. Bring back the wifi
7. Click the button "reconnect"

Expected behavior
The line "second line" is still there and saved.

Actual behavior
After going offline and after some delay, a spinner appears instead of the text editor.
Two error messages appear about being offline.
One of them has a button to reconnect.
After reconnecting the wifi, the "second line" is gone and the file has an older state with only "first line".

Other bugs in the area:

• Reconnect after idle broken #3374
• File might not be saved if close is happening too fast #3404

Will add to the board with high priority.

For this issue in particular I think the steps in question might not have been send yet. So we need to keep them around and try resending them once the reconnection succeeds.

Might be something interesting to retest after the recent changes with y.js and session handling.

This probably got fixed by the recent changes in #4474. Since the original issue is from before the Yjs migration, I'll close it. If those things still happen, we should open a new issue to track them.
