New UI view search box filter works for the tree and version fields, but not the branch field.

In the main "tests by build" view, the search box filter works on the tree and version column, but not the branch column
e.g. if you type "eel" into the search box, you get no results
but if you type AGL, you get the expected results (edited)
or if you type 5.0 you get expected results
