[Dashboard] Switch to viewmode without saving changes isn't reversing the applied chart from the suggestions for lens visualization from edit visualization panel for upgraded dashboards(Happening only with certain visualizations?)

[bhavyarm]

Kibana version: 8.14.0 BC5

Server OS version: Chrome latest

Original install method (e.g. download page, yum, from source, etc.): from staging

Describe the bug: If you edit a upgraded dashboard -> edit a lens visualization -> change the chart type from suggestions and then decide you don't want it and click on switch to view mode after consenting to have your tragic decisions discarded by Kibana, dashboard still displays the newly picked chart.

Please note I have upgraded from 8.12.2 ->8.14.0(mix of saved objects upgraded from 7.x). And this is happening with only some visualizations(?) I am attaching the saved objects file.

@bhavyarm, have you found a more common way to reproduce this bug? Or does it only happen on certain upgraded panels?

There is a pretty good chance that this will be fixed by our work in the Embeddable refactor (Lens isn't on the new system yet.)

Putting this in the backlog to track it, but we will not prioritize fixing it unless it's easier to reproduce or we notice that it still happens after the lens embeddable refactor.
