Short description of error
expand functionality in the outliner doesnt work when using the outliners search functionality
Exact steps for others to reproduce the error
go to blend data mode of outliner
type in the name of a scene material
in the results try and expand one them by clicking on the triangle to the left of the result.
Makes the search functionality useless, because you have to clear the search box and then manually look for the entry if you want to do anything more than look at it.
