Sync storage stops working sporadically

[wmonecke]

I am facing a weird issue with sync storage. It does work for the first couple of minutes, then any update to a reducer is not getting persisted any longer. However, after some time it re-starts persisting.

Any ideas why this could be happening?

I am able to rehydrate with the state that was persisted at the beginning (when state seems to being written to storage).
I am only writing about 8kb to storage, so that is not the issue.

With localStorage I am not experiencing this issue.
