Bug: Focus issues w/ tabbing and Vimium

[terichadbourne]

As I was playing with Vimium today I discovered it was allowing me to select elements to focus that can't actually be clicked on to do anything. For example, C below is the whole nav, and E is a non-clickable tutorial name.

Only some pages appear to be showing the focusable nav element, while other don't:

If I just tab instead, it (as intended) never selects the non-clickable full nav element.

On the tutorials page, both M and P toggle the coding toggle, but there's no way to get to the dropdown in Vimium (I can get there by tabbing though).

By tabbing, I can get to the dropdown and make selections, but it doesn't have a focus ring:

And by tabbing I can get to a focus ring on the entire "Include Coding Tutorials" element but hitting return at that point doesn't make it toggle:

If I tab one more time, the focus ring is gone, so I assume it's on just the toggle piece, but hitting return there also doesn't toggle. The next tab gets me to the first tutorial card.

Note about the dropdown highlight from @ericronne :

The full menu doesn’t have to be outlined. Instead i would outline only the selected option with a high-contrast color such as the green you’re using. If you use a background fill such as you have here, the contrast with the default background should be higher (4.5:1). Either way, you don’t have to outline the full menu.
