Unexpected Revert Behavior

[Cheryl Wheeler]

I have two Gnucash files/books. Yesterday, I opened File A and then File 
B in two separate instances of Gnucash. After working on File A for a 
bit, I decided that I wanted to revert those changes, so I selected File 
 > Revert. Gnucash closed File A without saving (so, that's good), but 
then it opened File B, giving me two instances with File B. I expected 
it to reopen File A after the changes were discarded.

Is this a bug or design intent?
