TASK DESCRIPTION Wikibase has a useful feature where plain wikilinks in edit summaries are formatted with the label of the entity, which is very useful when looking e.g. at page histories: > `[[Property:P735]]: [[Q463035]]` → > given name (P735) <https://www.wikidata.org/wiki/Property:P735>: Douglas (Q463035) <https://www.wikidata.org/wiki/Q463035> F34662730: Screenshot 2021-09-30 at 15-45-26 Revision history of Douglas Adams (Q42) - Wikidata.png <https://phabricator.wikimedia.org/F34662730> F34662732: Screenshot 2021-09-30 at 15-45-51 Difference between revisions of Douglas Adams (Q42) - Wikidata.png <https://phabricator.wikimedia.org/F34662732> However, the way this is implemented actually affects all links on diff and history URLs – specifically, this includes links in page content shown on diffs. This causes performance issues (T140879: WMFTimeoutException when loading some diffs on Wikidata [Timebox 8h] <https://phabricator.wikimedia.org/T140879>), but it’s also undesirable regardless of that – the content of a page looks different in diff and regular views, which is strange. For example: Here’s the original appearance of my sandbox <https://www.wikidata.org/w/index.php?title=User:Lucas_Werkmeister_(WMDE)/sandbox&oldid=1505856440>: F34662778: Screenshot 2021-09-30 at 16-09-37 User Lucas Werkmeister (WMDE) sandbox - Wikidata.png <https://phabricator.wikimedia.org/F34662778> Then, I purged it without loading the result: `curl --data-binary @- 'https://www.wikidata.org/w/index.php?title=User:Lucas_Werkmeister_(WMDE)/sandbox&diff=1505856440&oldid=1463378660&diffmode=source&action=purge'` And then loaded the diff: https://www.wikidata.org/w/index.php?title=User:Lucas_Werkmeister_(WMDE)/sandbox&diff=1505856440&oldid=1463378660&diffmode=source And not only are there entity labels in the diff view – because this ends up in the parser cache, those labels will also be shown on subsequent non-diff views: F34662782: Screenshot 2021-09-30 at 16-15-14 User Lucas Werkmeister (WMDE) sandbox - Wikidata.png <https://phabricator.wikimedia.org/F34662782> We should fix this, and only apply this special formatting to links that are actually in edit summaries.
