Image Editor is jumpy when opening.

[eddiemoya]

When clicking Edit Image in the attachment editor, there is a flickering - that is, the new stuff gets added to the page before the old stuff has been completely removed, so there is a fraction of a second when the page gets pushed down.

Simple fix. Patch included ( hopefully i created the patch correctly this time :p )

You don't need to change the minified script. that will happen automatically

[eddiemoya]

Removed the change to the minified javascript.

Patch freshness. This is good to go.
