Open https://codepen.io/36degrees/pen/LYxQBbm or the attached example.html 2. Hover over both links of the links on the line “17px link / with colour change” - text decoration thickness property expands to 3px 3. Hover over both of the links on the line “19px link / with colour change” - text decoration thickness property only expands to 3px on the link with colour change. ## Expected Behaviour The text underline thickness should increase to 3px on all links when hovered. ## Actual Behaviour In this example, the text-decoration-thickness only increases to 3px on hover on links up to a font-size of 19px, unless the link also has a colour change on hover. The font-size at which the text-decoration-thickness property stops working changes depending on the thickness being set on hover. In the CodePen / attached example, text-decoration-thickness is set to 3px on hover and stops working at links of font-size: 19px. Other examples: text-decoration-thickness on hover: 2px font-size value at which it stops working: 15px text-decoration-thickness on hover: 5px font-size value at which it stops working: 27px 1749881 1 ap 2021-04-13 14:55:58 -0700 In Safari 14.1, the underlines for 19px+ links are not painted at all (but the color ones are). Not sure if we'd want to track this aspect as a separate bug. 1752235 2 webkit-bug-importer 2021-04-20 06:00:17 -0700 <rdar://problem/76895249> 1923915 3 ntim 2023-01-07 23:31:46 -0800 I have a fix for this. 1923916 4 ntim 2023-01-08 00:00:06 -0800 Pull request: https://github.com/WebKit/WebKit/pull/8372 1923917 5 ntim 2023-01-08 00:01:22 -0800 Submitted web-platform-tests pull request: https://github.com/web-platform-tests/wpt/pull/37799 1923968 6 ews-feeder 2023-01-08 13:14:10 -0800 Committed 258641@main (6be98ae1629f): <https://commits.webkit.org/258641@main> Reviewed commits have been landed.
