Bug 1756210 - Let native theme focus outline be controlled only by CSS. r=mstange

Browse source 
This might be a bit more controversial, but matches Chromium at least,
and it makes sense to me... Would've also fixed this particular bug,
though I think the previous patch is also desirable if devtools ever
wants to add `:disabled` locked states or so.

Depends on D140529
