{productname} {release-version} addresses this by updating the key handler registration to occur during the `init` phase, and additional checks now ensure that previously prevented events are respected.

=== Deleting a selection in a `li` didn't trigger `beforeinput`.
// #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.
