<p>When looking at revision comparison with "Split fields" and "Unified fields", it's missing some of the scope plugin value changes. It appears that the "Visual Inline" version is showing everything, but that should be double-checked.</p>
<p>Here are the images from that issue:</p>

<p><strong>NOTE: there is an unrelated bug that needs a separate issue - not all scope items are showing up in the "Split fields" and "Unified fields" versions of the revision comparison</strong></p>
