New ledger display oddity (git master)

[Jack Ostroff]

I'm not sure when I first noticed this, but it hit me again today.  If  
I go to the Categories View and double click on a category, it switched  
to the ledger view of that category - but the Account Name drop-down at  
the top of the ledger displays the last regular account which was shown  
in the ledger.  This got me really confused for a while until I  
realized that all these yellow and purple transactions were in the  
category, not in the listed account.  It's rather minor in the scheme  
of things, but did cause me some head scratching until I realized it  
was just a display issue.

I'll be glad to open a bug for this if it needs tracking.
