Steps to reproduce:
Expected:
You can preview all content.
Actual:
Categories, language links and indicators are missing.
| Subject | Repo | Branch | Lines +/- | |
|---|---|---|---|---|
| Show simple category list in preview | mediawiki/extensions/VisualEditor | master | +21 -1 |
And also {{DISPLAYTITLE:}}, which currently is omitted, too.
A real test case is https://de.wikipedia.org/wiki/IPhone?veaction=editsource, a minimal
{{DISPLAYTITLE:foo}}
<indicator name=foo>foo</indicator>
[[Category:Foo]]
[[fr:foo]]To expand a bit on why seeing the categories would be useful: when adding them via VE, if you're adding a new category that doesn't exist, this is obvious both because the interface tells you about it while you're adding it (and can prevent you from making a mistake if this is the case), and because the related link is red.
A preview with categories also answers questions like: "Does the {{Infobox Town in XY}} add a [[Category:Town in XY]] automatically or do I have to add it manually?"

[mediawiki/extensions/VisualEditor@master] Show simple category list in preview
Even with Wikidata they are especially useful to see if you accidentally added an interwiki link by forgetting a leading colon in a link.
Change 359646 merged by jenkins-bot:
[mediawiki/extensions/VisualEditor@master] Show simple category list in preview
Categories are shown in preview, but only if they are added directly ([[Category:Use British English]]) and not if they're added by transclusion ({{Use British English}}).
Was this reverted at any point in time? I can’t see any categories in the preview in 2017 wikitext editor, not even those that weren’t transcluded from a template.
I do see categories in the 2017 wikitext editor preview, so it's up to you to check again and provide an example if they are really missing in some cases.
Sure:
Very interesting. I can reproduce with your example and many other Russian articles, but not all. E.g. https://ru.wikipedia.org/wiki/Zing!_Went_the_Strings_of_My_Heart?veaction=editsource has the categories in preview. I never had this issue in German Wikipedia, and I can't reproduce in English and French, either.
