Disable autosave while viewing an older version in Version History

We experienced a serious issue where a browser tab was left open while an older version was selected in the Version History sidebar. After the 30-minute autosave interval, Figma created a new saved version based on that older state, effectively overwriting several days of more recent work in the current timeline.

Fortunately, the version immediately before the autosave still contained the correct work, so we were able to recover it. However, this was understandably alarming for the designers, and it is easy for someone to trigger accidentally just by reviewing previous versions and leaving the tab open in the background.

I’d suggest disabling autosave whenever a user is viewing an older version in Version History. Autosave should only resume once the user explicitly returns to the current version. At minimum, Figma should provide a prominent warning that the user is viewing an old version and that leaving the file open may create a new save from that state.

This would make version-history review much safer and help prevent accidental rollback-like saves.
