Hi,
I'm having troubles with keyboard navigation on filter bar cell.
Basically the keyboard navigation works a bit funky. If I'm located on the filter bar and wish to move through it using the keyboard it starts skipping columns (and sometimes even rows). Try to navigate to the filter bar from somewhere in the grid using the keyboard, and then try to move left or right, I'm sure you'll see it.
I've attached a file for you to check it out.
