History navigation in sheets do not seem to work if you are in "strict" mode

[ldubost]

Description

If you switch your sheet to "strict" collaboration mode, then when navigating history all seems to stay at the state of the last checkpoint.

For example in this spreadsheet, there are no checkpoints, but there are changes

Try to navigate the history in "rapide" mode it works.. But in "strict" mode you get a blank sheet when rolling back the major version and then all stays blank when you advance.

Steps to reproduce

1. Create a blank sheet
2. Verify you are in "rapid" mode
3. Add content (repeat for multiple cells)
4. Open History
5. Click << to get back to the first version (which should be empty)
6. Advance in history using > and you see you changes appear
7. Close history
8. Switch the "strict" mode
9. Open History
10. Click << to get back to the first version (which should be empty)
11. Advance in history using > and you see you the sheet stay blank
