1512144 - Element that is focused is not always fully visible in viewport

Status: RESOLVED DUPLICATE of bug 637017

(Firefox :: Untriaged, defect)

Description

[hidde]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:64.0) Gecko/20100101 Firefox/64.0

Steps to reproduce:

1. Use tab to navigate between interactive elements on a page
2. Tab to something that is at the bottom of the viewport


Actual results:

Sometimes the element is partly hidden, sometimes a URL tooltip overlays it.


Expected results:

When an element gains focus, the browser should scroll enough for the element to end up fully in view, preferably a number of pixels above the bottom edge of the viewport, so that it cannot be obfuscated by the URL tooltip, and the full thing is visible.

I feel it is not exactly the same as 637017. That issue is merely an example of something that, I think, is a wider problem: the browser window's scroll position doesn't give focused elements enough space.

Not sure if that is something that we could consider addressing as a separate thing though?
