Template "Modified" mark problem

Hi

I created implementation from IEmailTemplatePreviewPlugin

I truing to change data inside templates but can't save it.

I found, that data send to server ONLY if template marked as "Modified", but I see any my changes do not fire "Modified" state.

I tried to "revert all templates" but after "Save" they still have previous values.

And no related exceptions

PS On OOTB extensions works fine
