246338 2022-10-11 07:28:35 -0700 [css-contain-intrinsic-size] Apply the value of css contain-intrinsic-size to <select> 2022-12-11 12:06:22 -0800 1 1 1 Unclassified WebKit CSS WebKit Nightly Build Unspecified Unspecified RESOLVED FIXED InRadar P2 Normal --- 246944 236707 1 cathiechen cathiechen webkit-bug-importer oldest_to_newest 1904777 0 cathiechen 2022-10-11 07:28:35 -0700 `<select>` adjust the style in RenderThemeMac::adjustMenuListStyle, which might change auto values of width and height to fixed values in the style. The values of contain-intrinsic-size specify an explicit intrinsic inner size of <select>, which does not affect the layout size of <select> if there are fixed width and height. We should found a way to make contain-intrinsic-size effective to <select>. See test case: LayoutTests/imported/w3c/web-platform-tests/css/css-sizing/contain-intrinsic-size/contain-intrinsic-size-032.html 1906455 1 webkit-bug-importer 2022-10-18 07:29:30 -0700 <rdar://problem/101290328> 1907112 2 cathiechen 2022-10-20 11:28:31 -0700 The case 1 fails because `border: solid;` changes `part` from `MenulistPart` to `MenulistButtonPart` in `RenderTheme::adjustStyle`. Then it goes different path: ``` case MenulistPart: return adjustMenuListStyle(style, element); case MenulistButtonPart: return adjustMenuListButtonStyle(style, element); ``` After style adjust, the appearance is different. It seems WebKit is using `RenderStyle::borderAndBackgroundEqual` to decide which appearance. I'm not sure if we should touch this part. 1907773 3 463194 cathiechen 2022-10-24 05:53:33 -0700 Created attachment 463194 WIP-patch This patch is based on https://github.com/WebKit/WebKit/pull/1799.
