Bug Skill Casting Frame shows no available skills

[Veracity]

I am in Zootomist, but I really do have a few skills available.
Especially, many via my august scepter.

When I first log in, I see lots of skills on the Skill Casting frame.
And then, it seems to forget them all.

Here's an image of the frame in that condition:

The only one it shows is the last skill I cast via the frame.

I logged out and back in again and now it looks like this:



Note the scroll bar; there are lots of skills both above and below.

OK, that text box labeled "Skill Name" is an "AutoFilterTextBox". If you type in it, it will filter the list to only have things that match.
Thus, if I type "Milk", I'll see Milk of Familiar Kindness and Milk of Familiar Cruelty.
If I select one of those and cast it, the text in the box will become that skill - and there will only be one skill in the dropdown.
If I clear the text field, voila! all the skills are there again.

What's weird in my example is that there is nothing in the text box - because I cast the skill from the maximizer - but the dropdown still only shows a single element. It makes me think that the text box has its own state which is causing the filtering but is now showing up in the GUI.
