Bug 90159 – user-select: none cursor turns to I-beam on mouse dragging

• Status: RESOLVED
• Resolution: INVALID
• Component: UI Events

[Yves Van Goethem]

Observation:
When you start selecting an area that has user-select:none; and drag the cursor around, it changes to a text cursor.

Expected:
The cursor should be default as defined.

This has got nothing to do with user-select:none. The bug here is cursor type being changed to text cursor(I-Beam cursor) during selection, even when the cursor type is explicitly set to be something else.

This is committed in blink https://codereview.chromium.org/23461040/

It seems like this is done intentionally. I'm not sure changing this behavior is desirable.

[Ryosuke Niwa]

Hm... looking more closely, maybe this is a regression from http://trac.webkit.org/changeset/11490.

We should probably rephrase this comment to something along the line of "use an I-beam regardless of the content beneath the cursor when cursor is not explicitly specified."
since now we're respecting cursor CSS property during text selection.

The description can be outside of this if.
It would be nice if you had something like debug("This test requires eventSender") in the else clause. Better yet, explain how to manually test it.

As I suspect, the old behavior was indeed intended.  Revering the patch.
