1 Create a folder with multiple files in.

2 Use the keyboard to tab through it.

EXPECTED: There should be exactly one tab stop per file.

ACTUAL: There is a tab stop to the left of the file that does the same thing as the tab stop on the file.

For example, in the attached image (taken from the Mount Orange school demo), the file silly.jpg is currently focused. This is correct, but from this point it now takes 2 presses of the Tab key in order to get to the next file test_procedure.txt; it should be only 1 press. If you press Return on the intervening tab stop, it actually does the same thing as if you press Return on the file (downloads it).

It is a minor accessibility bug to have two tab stops for the same thing, because for users who have to navigate with difficult input devices, it increases effort if they have to tab twice. (Also, in this case, the unnecessary tab stop is actually invisible with no focus indicator, which breaks WCAG 2.4.7.)

Note: Unless somebody else picks it up, I'm planning to assign this to an OU developer to work on.
