If you type in the material library search bar as soon as you type if it finds a match within the first 3 letters the focus shifts and you cant finish your search terms.
For instance if i type the word 'leather' often it will search 'le' before it shifts focus from the textbox and before get to finish the word. It will only show me 'simp(le) car paints' because im assuming its filtering in category order and they are the first ones the algorithm finds?
