            Bug ID: 192621
           Summary: messed up scope in eventHandler
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Major
          Priority: P2
         Component: Event Handling
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: etasho at gmail.com

On Chrome 71 (not on any Chrome before), if an element (select, button) has an inline onclick event with the id (of the element) specified as a parameter of the called function AND this element has children elements, the scope gets messed up and it tries to take the id of the child element.

<select id="myselect" onclick="jsDoSomething(id)"><option>1</option><option>2</option></select>

function jsDoSomething(id) {
   alert(id);
}
