Keyboard navigation does not work correctly with search

Steps to reproduce:

• Open the attached project
• Open Material Browser, Material Editor and Texture Editor
• In Material Browser, type "copy" to search
• Two matches found from materials: "test copy" and "some copy" -> click the first one to select
• Press right arrow key in keyboard to navigate to "some copy" material
• -> would expect that "some copy" material is selected, but instead selection goes to "some" material which is not visible in Material Browser.
• Navigate forward/back with arrow keys
• -> seems to navigate through all materials and textures even though those are not visible after search
• Please see attached recording
