Steps to reproduce:
* Start making changes to a page in the classic editor.
* Use the normal "Show preview" or "Show diff" button at the bottom
of the editor. The page reloads and now shows a preview/diff at
the top, above the editor.
* Now start using the realtime preview feature on the right side of
the editor.
You will notice that the preview/diff above the editor starts to
flicker, but is never updated. (There is no need to update it. The
realtime preview that is updated is the one in the right pane.)
The original code was added via T293347. I believe the flicker
exists since then. It's effectively a misconfiguration. I hope the
comments make this clear.
This is also a direct follow up to T307046 where the diff view was
fixed (it just disappeared before), but flickers since then.

The #wikiPreview element can contain other child elements such
as the already-removed one of .previewnote but also (on category
pages) category lists, which we don't want.
This changes to only clone the specific content element. We could
just create this in JS, but don't at this point have access to
the lang direction.

Because the manual-mode bar gets hidden when an error message
is displayed, it's necessary to re-show it after the preview
is reloaded from the error message. This was done in the
below patch, but that didn't account for all conditions.

auto-load is stopped.

that shows on hover in the realtime preview pane is clicked.

* Always hide the error message after a successful preview.
* Before previewing, make sure the preview node is un-hidden, in
case it was previously hidden by showError().
* Stop checkResponseTimes() from hiding any error (it only handles the
manual mode).
* Stop showError() from hiding the manual bar (it's okay to see both).

After three slow preview requests, switch to showing a bar at the
top of the preview area that contains a manual 'reload' button.
The manual bar will be hidden when an error message is show, but
re-shown again after the error is dismissed. Closing and
re-opening the preview pane doesn't reset the manual mode.

scrolled), and also an accesskey to trigger the preview. If the
preview is not open when the accesskey is pressed, it'll be
opened.

$wgWikiEditorRealtimeDisableDuration is introduced which allows
sysadmins to control the average time after which Realtime Preview

intentionally not localized. In a future patch, we will force the
user into a 'manual preview' workflow. See T304568 for more.
