Search button overlaps right nav
Similar to this answer about how adding a comment overlays right nav, and this one with edits, and yet another one with another set of buttons.
Firefox 62.0, Windows 10, happens (roughly) between 1001px and 1136px wide: resizing the window makes the search button from the search results overlays the right nav.

I don't know if it's relevant but apparently it also happens on job searches, per this post on MSO, but that was another browser and not the exact same button - never used job search on SO, don't know how it behaves.
