Steps to reproduce:

1. Open the Bagnon bank frame.
2. Select any character other than the current one to view their bank contents.
3. Close the Bagnon bank frame.
4. Click on a bank NPC.

The bank frame opens to the last viewed character instead of the current one.

Ideally, closing the frame (any frame) should always reset it to the current character, but at the very least, clicking on a bank or void storage NPC should reset the bank or void storage frame to the current character along with opening it.
