Comment (by JavierCasares):

 Replying to [comment:1 kjellr]:
 > I've added [attachment:"49322.patch"] to fix this issue. It adjusts the
 `z-index` of `#site-header` from `1` to `2`. The `z-index` of the cover
 block's overlay is `1`, so that's enough to fix the issue. Adjusting the
 `z-index` of any items below `#site-header` didn't have any positive
 effect, and making this change doesn't seem to mess with anything else
 that relies on `z-index`(like the search box for instance).

 Tested and works for me :) Thanks @kjellr
