Footer links not clickable

[jsha]

Steps to reproduce:

1. Visit any recently built docs.rs page, e.g. https://docs.rs/rushterm/0.5.2/rushterm/.
2. Scroll to the bottom of the page.
3. Click "About docs.rs", "Privacy policy", or "Build queue".

Expected result: navigate somewhere else.

Actual result: no navigation.

@GuillaumeGomez could this be related to #1579 ? Or something else?

The footer is before the main div and on new docs the main div padding extends down over it. Looks like either moving the footer down below the main div, or adding a high z-index to it, fixes it for both old and new docs. (Or maybe there's a way to not have the padding extend down over it on the new docs too, the old docs appear to have it stop significantly above the footer somehow).

I think changing the z-index is the right fix here (other fixes might be much more complicated).

EDIT: sending a fix.
