Map stash tab can't highlight matched map class, and can't stablize when search with keywords

Example, one originator map in Academy class and one originator map in Beach class, search "orig", and click the map class one by one.

First, both Academy and Beach only highlight after you click it;

Second, scroll down pass Beach, when you click one of the map classes below, it shows the maps under that class and immediately scroll back to Beach, i.e. the last highlighted class.

Both make the search in map stash tab intolerable.
