Bug 173909 – Incorrect behavior of "cursor: auto" over links

• Status: REOPENED
• Component: CSS

[Florian Rivoal]

The "auto" behavior of the "cursor" property used to be only vaguely defined, but to improve interoperability, the latest specification is more clear:

> auto behaves as 'text' over text, and 'default' otherwise.

Other expected effects, such as the "pointer" cursor over links should be achieved using the UA stylesheet, rather than through the magic behavior of the "auto" value.

Webkit uses "auto" rather than the UA stylesheet to adjust the cursor, which causes the following tests to fail:

https://test.csswg.org/harness/test/css-ui-3_dev/single/cursor-auto-002/format/html5/
https://test.csswg.org/harness/test/css-ui-3_dev/single/cursor-auto-003/format/html5/

This is now being fixed in Chrome, it would be good if Webkit fixed it as well. See https://bugs.chromium.org/p/chromium/issues/detail?id=737452

Webkit is missing following patch change to HTML.css file:

https://github.com/WebKit/WebKit/blob/main/Source/WebCore/css/html.css#L1289

Commit - https://chromium.googlesource.com/chromium/src.git/+/902ef4e53edcb011944f0f7cc3cd9a7d43b21759

While I was not able to find this change 1:1 since code has changed a lot:

https://chromium.googlesource.com/chromium/src.git/+/74ef53b06b1e1f1e775371296c3457f54a2b9eba%5E%21/#F0

This was earliest of the patch - https://chromium.googlesource.com/chromium/src.git/+/53a46aede88dac4189a493f1e6eb30868aa17929

I am not sure whether it is fixed or not but I can see that there are some difference in current Webkit code (especially html.css). I would leave it to someone else to confirm whether it is something yet to fix or not. Thanks!
