I can reproduce it by simply narrowing the window of my browser on my desktop:

#### When sufficiently wide:

#### A bit narrower, and a few weird things happen (sidebar / header go white) which I’m not super sure is intentional:

#### Narrower highlights the problem (i.e. folding phone size)

#### Very narrow (normal phone size) is fine again.
