Because we have outline-offset in html.css?

input:focus, textarea:focus, isindex:focus, keygen:focus, select:focus {
    outline-offset: -2px
}

We still have this issue:

Removing this above makes both ‘select’ element looks same in Minibrowser - if I delete below UA stylesheet rule. Will attach screenshot.

It was added to preserve existing behavior (patch was landed in 2016 while this bug was filed in 2013).
