It looks like it's pulling from the MDN docs for the dataset (the grid and language are identical.) In this case, it's not going to be up to date, because MDN has fallen behind. For example, MDN still lists container style queries as unsupported by Safari, but Safari has supported them for three months. e.g. https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_containment/Container_size_and_style_queries https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_contain... https://bugs.webkit.org/show_bug.cgi?id=246605 https://bugs.webkit.org/show_bug.cgi?id=246605 Because of stuff like this, the gold standard is caniuse.com, not MDN.
