Status: RESOLVED FIXED

(Core :: DOM: UI Events & Focus Handling, defect)

Attachment: Patch v1.0

This is spinning off from bug 552707.

Open the testcase:

> data:text/html,<input onclick="alert('click event fired');" style="border: blue solid 10px;">

Press left mouse button on the blue border and move the cursor into the editor and release the mouse button, then, onclick event must be fired.

At mouse up event handling, the content is anonymous div but the mouse down content is <input>. Therefore, the content mismatch causes to cancel the click event. At the checking, if the current content is a root of anonymous subtree, we should also check whether the parent content is mouse down content or not.
