Bug: Editing in multiple windows causes edits to overwrite

[jayshao]

Observed behavior is edits from multiple windows/multiple machines, if not aggressively refreshed can overwrite each other. This shows up as deletions in the git history.

While somewhat obscure - my most common (personal) editing flow is to open 2 tabs on 2 screens - one I tend to use to look at stuff in the file, and the other to edit. Or switch between a work and commuting laptop - in both of those scenarios I unintentionally overwrote previous edits.

Some kind of attempted merge if hashes didn't line up, or at least a warning would be preferable

This behavior has become increasingly problematic for projects with multiple people trying to edit specs (esp. when doing bug squash / tech editing) to the point where we have started funelling all edits through a single person - bypassing much of the benefit of using a tool...

Hey @jayshao in the v4.8.0 we made some progress on the alerts that let you know others are editing, especially when you are open in multiple tabs, so hopefully this happens less.
