Can you fill out the PR template? |

Yes, sorry, was using github.dev to make the edit and it doesn't surface that. ^_^ |

Great, thanks! Can we add UA stylesheet tests similar to web-platform-tests/wpt#33917 ? |

There was a problem hiding this comment.
svg should be in the SVG namespace

Thanks Simon for working on the tests! It looks like there are no browser bugs filed for Safari or Firefox, and the one filed for Chrome is closed. However, nobody passes any of the tests currently. So, can we confirm that there is multi-implementer support for this change, and get appropriate bugs filed for it? |

cc @emilio @smfr @chrishtr for implementer interest. (Also see w3c/csswg-drafts#7144 (comment) ) |

From WebKit/standards-positions#8 (comment) it seems like this is under discussion in the CSS WG and they might end up with another solution? |

Per the resolution in w3c/csswg-drafts#7144, we're modifying the behavior of 'overflow' to actually do something on replaced elements, so they can paint outside their bounds. The necessary CSS definitions have been updated in w3c/csswg-drafts@a679cd1, but we additionally need some additions to the UA stylesheet to support it.
