It always returns the form-node, where it should return the input-elements Reproducible: Always Steps to Reproduce: 1. Create a page with a <form> and some <input>'s in the form 2. Add window.onload javascript with an event-handler that logs the window.getSelection().focusNode on every keyup Actual Results: Notice that the logged node is always the form-node Expected Results: The logged node should be the specific input-node
