See https://wpt.fyi/results/css/css-sizing/contain-intrinsic-size?label=experimental&label=master&aligned

Safari fails a bunch of test cases even though they all claim to be passing in WebKitTestRunner:

In fact, these tests are passing in WebKitTestRunner / DumpRenderTree but fail when ran inside MiniBrowser or Safari. I have no idea what on the earth is happening here...

The failures are expected, we haven't enabled content-visibility on Safari, but it is enabled on WKTR. (The failing tests rely on content-visibility)
