Expanded tree not persisted under certain circumstances

[Surfrat]

I am using ExtPersist to save the tree state on refresh or when you navigate away and back to the original page.

I start with this:

A page refresh returns me to the same state. Test passed.

A "navigate away and back" gives me this:

Test failed as I expect to see the same state as in the first screenshot.

The reason it fails is I have
documentsTree.reload();
in my page activate event.
If I remove this line then the state is correctly restored.

I see this issue has been previously reported here.

Is there a fix for this or is it on the road map?

Thanks.

I hope this is explained here #638
If the problem yet exists, please create a jsFiddle or similar, so I can debug it,
thanks!
