Vendor item list doesn't reset scroll when filter entered

Reproduction Rate: 100%.
Blocker? No.

Details:
If you scroll the vendor item list and then afterwards type in the filter textbox, it doesn't reset the scroll, so if there is an item you're searching for the listbox can appear empty to the player when its not.

Screenshot of the list scrolled to the top.

At the top with a search filter.

The list scrolled a third down.

Doing the search again, the list appears empty; this is because the scroll isn't reset to the top.


Steps to Reproduce: Scroll the item list down and then enter text in the search filter.

The same is true for the player inventory list and everything else I believe.
