=== Description
After the proposed changes in T276566, the search icon at lower resolutions when clicked will take the user to the search page.
With some changes it should be possible to wire this up in such a way that it operates as it does at higher resolutions.
After talking to @alexhollender we will likely make this behave similar to mobile - e.g. open an overlay. This will likely require a slight change to our wire up and a new component.
=== Design
Basic demo:
{F34480722 width=400}
=== TODO
[X] @alexhollender to provide mocks
[x] Engineer to analyse and provide a suitable approach and fill in developer notes
=== Developer notes
See commit message of https://gerrit.wikimedia.org/r/699462 for the challenges on this one.
# Acceptance criteria
[] Add a dedicated toggle button
[] Wire up toggle button to load and show/hide the search interface
[] When search is open the hamburger and logo is obscured underneath
[] When search is open the user links are visible (tricky bit)
