form restore doesn´t keep taxonomy / category field values

Issue Summary

Hi,

I think form restore together with Add and Reference is a great module. It actually solves exactly the problem I had designing my use case.

But unfortunately it doesn´t keep all the values. I have some taxonomy fields (categories) in the first form. After submitting from the second form and coming back to the first the values are gone.

Any idea why that is?
Is there an easy way to solve it?

I´m a bit surprised that there are no bugs or feature requests. I sno one using the module?

Thanks for your help

Jochen
