Can this page – https://developer.mozilla.org/en-US/docs/Web/API/Document/onselectionchange – be deleted? (Or if not, should it have a companion Document.onselectstart
page?)
MDN already has a page for the onselectionchange
event handler at https://developer.mozilla.org/en-US/docs/Web/API/GlobalEventHandlers/onselectionchange. This seems more appropriate, based on the spec: https://w3c.github.io/selection-api/#dom-globaleventhandlers-onselectionchange.
