Pressing on Filter button doesn't allow button navigation

[iamthemulti]

When pressing on the Filter button in the Movies tab, you can't navigate the Filters menu using just arrow buttons on a remote control. The workaround I have to do, is use the Magic Remote (shake remote to get a pointer), hover over a selection (such as "Tags"), then I can use the arrow buttons as expected.

A fix would likely highlight one of those selections by default so you can navigate them freely.

Tested on LG C2.
