[2020] Vendor search/filter stops working if you go into/out of a monolith/arena

I’ve attempted to reproduce this issue, but found the search bar worked fine if I cleared the current search and typed a new one. If searching stopped working for you entirely, I’d appreciate you uploading your log file if it happens. again.

In my experience the bug only happens when the shop rotates out its items. The search isn’t automatically refreshed when the shop re-opens. It probably makes sense to just clear the search bar when the window closes, like is done with the skills window.
