Hi greetings, I would like to report a bug in the special page Special:PagePreparation. When we try to prepare pages for translation through this, it does not prepare categories for translation.

Reproducing the bug

*Open Special:PagePreparation
*Enter the name of a page for preparation (page should have at least one category)
*Click prepare.
*The page will show the prepared version with translate tags, markers, repaired links, etc.
*In this diff the the wikilinks of categories will be appended with a template {{#translation:}}.
eg:[[Category:Example{{#translation:}}]]
*Click publish.
*The page will be published
*When we open the page in edit window (ie the published version) the category markups remain as previous
ie. the template {{#translation:}} will not get appended.

Please consider this issue.
