Autosaving sometimes failing silently on google drive storage

[gberche]

I have experienced multiple times that the autosaving feature does not work on google drive storage: the animated gif keeps tuning and saying "autosaved" but under the hood the document is not saved.

The "file-> save" button is greyed out.

The workaround to not loose modifications is to save as another document "file-> save as -> google drive".

At times, the UI properlyn says "google drive session timeout, please refresh the page before doing modifications". I don't remember if in this case the save button is also greyed out.
