Problem: While using tabbing navigation functionality, the time frame filter lacks a highlight state which can cause accessibility users to miss that functionality of the forum.
Repro Steps:
Navigate to the forum home page
Select the Top sub-menu filter
Press tab until you reach the end of the sub-menu
Tab once more and observe that the highlight state disappears.
Observe that the arrow keys will scroll up and down the page here
Tab again and observe the highlight state is still absent
Observe that the arrow keys will open up the time frame filter, indicating that the focus, while invisible, is on the filter.
Expected Results:
A highlight box should be present on selected UI elements so accessibility users can accurately navigate the forums.
