Example:
- Mouse listeners on document
- Listeners append text nodes + br to a div with `container.innerHTML += ...`
Expected result (based on tests with Chromium and Firefox, not sure if it's covered by the spec, though):
- Clicking the div content triggers mousedown+mouseup+click in sequence
Actual result (tested with multiple WPE browsers, as of 282132@main):
- Only mousedown+mouseup get emitted.
- Click emission gets stopped in EventHandler.cpp::targetNodeForClickEvent(mousePressNode, mouseReleaseNode), with mousePressNode (through m_clickNode) null, as it gets replaced in the += operation of the JS listener.
Using `container.insertAdjacentHTML("beforeend", ...)` allows the originating nodes to live and the click gets delivered.
Is this a bug on WebKit side or is it something not yet covered by the spec?

Laura, it would be great if you could upload a test case for this.
