Comment 2 Abrar Rahman Protyasha 2023-10-10 04:24:13 PDT

There is a web compat risk associated with changing WebKit's behavior to what this test expects. Refer to https://github.com/w3c/uievents/issues/278 for extended discussion.

Having said that, it is well understood that calling `preventDefault` on `mousemove` events should _NOT_ prevent `selectionchange`.
