Comment:

 In [changeset:"51595" 51595]:
 {{{
 #!CommitTicketReference repository="" revision="51595"
 Editor: Preserve the original template keys when preparing a list of page
 templates.

 Previously, the original "404" template key was lost when "Default
 template" is merged into the available templates array, as the
 `array_merge()` function renumbers numeric keys. Later, when we merge
 templates on the client side, this caused duplicate "404" templates to
 appear in the dropdown.

 By replacing the `array_merge()` call with `array_replace()`, we make sure
 to keep the original numeric keys.

 Props Mamaduka, Toro_Unit, youknowriad.
 Fixes #53898.
