My own 2c. solution is to have the preview at the top of the page and an 
anchors jumping to the edit form itself when required:


===8<---[Site.EditForm]---
(:if e_preview:)
>>float=right bgcolor=#fff7cb border='1px solid #ffad80' padding=2px 
>>center<<
'''$[Preview]'''\\
%red%[[#edit | &#9660; $[Edit] &#9660;]]%%
>><<
(:e_preview:)
----(:if:)[[#edit]]
!$[Editing {$FullName}] %block class=wikiaction% \
[-[=[=][[Rename -> {$FullName}?action=rename]][=]=]-] \
[-[=[=][[Delete -> {$FullName}?action=delete]][=]=]-]

(:messages:)
(:div id='wikiedit':)
(:input e_form:)[[#top]](:e_guibuttons:)\\
(:input e_textarea:)\\
$[Summary]: (:input e_changesummary:)\\
$[Author]: (:input e_author:) (:input e_minorcheckbox:) $[This is a minor 
edit]\\
(:input e_savebutton:) (:input e_saveeditbutton:) (:input e_previewbutton:) 
(:input e_cancelbutton:)
(:input end:)
(:divend:)
(:include $[{$SiteGroup}/EditQuickReference]:)
===8<------
