Tests: https://github.com/web-platform-tests/wpt/pull/11264 Spec: https://html.spec.whatwg.org/multipage/rendering.html#tables-2 Use case: Filtering a table and using the "hidden" attribute to hide rows causes the widths of the columns to change if it's hidden by display: none. With visibility: collapse the widths of the columns do not change. (Type something in the filter of https://bocoup.github.io/wpt-disabled-tests-report/ for a demo.)
