+// #TINY-12793
 
+Previously, deleting a selection inside a list item or pressing Backspace at the start of a list item did not fire the native `beforeinput` event. The editor's list key handler prevented the `keydown` event before performing the deletion, which also suppressed the `beforeinput` event. This affected integrations and plugins that relied on `beforeinput` to intercept or customize deletion behavior in lists.
+
+In {productname} {release-version}, the editor now dispatches a synthetic `beforeinput` event before performing delete operations inside list items. Handlers can call `preventDefault()` on this event to intercept the deletion as expected.
