Make/Meta search input outside bounds of responsive menu

[coffee2code]

The sidebar search widget on Make/Meta is almost completely outside of the bounds of the responsive menu. Only the leftmost few pixels of the search input are visible (enough that the field can be seen and clicked into). There is no reason the search widget shouldn't be shown (it is for other Make sites), so therefore should be shown aligned with the other menu and sidebar offerings. See attached screenshot.

Unlike most (all?) other Make sites, which use a legacy search widget in their sidebars, Make/Meta makes use of the Search block. This leads to the aforementioned unexpected display of the search block in the responsive menu due to styles originating from Gutenberg.
