The attached test case shows that the width of the caption is wrong when it computes to 'auto' or '100%' and the table has vertical borders.

In the "100%" cases, Firefox might be trying to follow this sentence from CSS2.1 17.4: "Percentages on 'width' on the table are relative to the anonymous box's containing block, not the anonymous box itself", as it makes the caption as wide as the body.

The caption width is also wrong (by 5px or so) when the table has any horizontal padding at all--even if the caption is given the same padding.

Created attachment 21258 [details] Percentage width Caption bug. percentage based width of the caption is using the table as the container not the element containing the table. In this example I have set the table width to 50% and the caption width to 50%. This is showing the caption at 50% of the table width (25% of the page width). Where in all other browsers it is showing the caption and the table at 50% of the page. Indicating that the caption should be contained by the page not the table. Can anyone confirm the W3 recommendation on this?

Is bug #38358 a dupe of this? Bug present also on GNU/Linux with latest Epiphany and Google Chrome.

Created attachment 460384 [details] Safari 15.5 matches with Chrome but differs from Firefox Based on attached test case in Comment 01, Safari 15.5 matches with Chrome Canary 105 but differs from Firefox Nightly 103 as shown in the attached screenshot. NOTE - Firefox Screenshot is cut half but the "red" box extend beyond visual viewport. I am not clear on expected behavior and which browser is behaving right but appreciate if someone can have a look and update in quick summary on what is expected behavior inline with web-spec. Thanks!

This would deserve a WPT test case.
