Automatic update from web-platform-tests [Editing] Fire selectionchange event on TextControl for backspace input The selectionchange event does not get fired when the backspace key deletes text inside a textcontrol element. According to the specification [1], when an input or textarea element provide a text selection and its selection changes (in either extent or direction), the user agent must schedule a selectionchange event on the element. This change ensures that the event will be scheduled as per the specification.
