Bug ID: 235672
Summary: avoid setting and clearing :active state when
dispatching synthetic click events when possible
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: DOM
Assignee: webkit-unassigned at lists.webkit.org
Reporter: heycam at apple.com
Simulated click events are dispatched with two options:
* whether to send associated events mouseover, mouseup, mousedown
* whether to repaint the target element with its pressed look
We currently always set the element's :active state just after when we'd send the mousedown event, and clear it just after that.
When we dispatch a simulated click event with neither of the above options set, there's no way to observe the temporary :active state on the element. We can skip it in that case.
Forthcoming is a 0.3-0.4% improvement on Speedometer 2.
