636214 - setting style.cursor with a data URL doesn't work

Status: VERIFIED INVALID

(Core :: Layout, defect)

Description

[Josh Aas]

Attachment: test case 1

The attached HTML test case tries to set a node's "style.cursor" to a data URI in a button's onclick handler. Works in Chrome, doesn't work in Firefox. What do we need to do to make this work? I suspect this bug can be duped.

Doesn't work on Mac OS X or Windows.

The "cursor" property syntax is 0 or more URIs, each followed by a comma, followed by one of the predefined cursors as a fallback.  Note the CSS parse error the testcase generates.

Spec is at http://www.w3.org/TR/CSS21/ui.html#cursor-props

The CSS 2.1 test suite seems to have no tests for this.  Can we still add one?

Comment 4

[Josh Aas]

Thanks! Specifying a predefined fallback makes this work.

We can submit additional tests, but they won't be added to the test suite until after the version of the test suite used for entering PR.  (I'm not sure if the test suite repo has a place to put such tests...)

I think that's fine; we should just get the tests added.  fantasai, where should they go in the repo?

Put them in an incoming/ folder instead of submitted/.
