Hi, iOS 14.5 introduced an important regression that caused white space: nowrap rule to be ignored under some circumstances. I have created a reproducible case here: https://jsbin.com/xotenexebe/1/edit?html,css,output Prior to iOS 14.5 and any other browser, the list is properly scrollable. Starting from iOS 14.5, the white-space: nowrap rule is completely ignored and items are stacked.
This is fixed with r272412 (https://trac.webkit.org/changeset/272412/webkit)
