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? (Example incoming)
