Comment:

 In [changeset:"48210" 48210]:
 {{{
 #!CommitTicketReference repository="" revision="48210"
 Customize: Ensure the default message in `LockedNotification` is set to a
 string instead of `null`.

 This avoids a JS error when passing the message to `wp.a11y.speak()` when
 showing the "changeset is locked" overlay to prevent two users from
 editing the same changeset simultaneously.

 Props dlh.
 Fixes #50500.
