Change d7fe3f896f545a3047528ee9eba37087b1382c13 broke diffs for Items completely, only the JSON diff is shown. The reason is that Wikibase\ItemContentDiffView needs to extend Wikibase\EntityContentDiffView instead of DifferenceEngine. But there seem to be additional issues.
fixed by change I8f2e03cc
