Change Details

Currently the module `mediawiki.page.watch.ajax` is loaded on all pages when the general preconditions are present. On pages without a watch button this module is useless. For example: * [[ https://en.wikipedia.org/wiki/Special:WhatLinksHere | Special:WhatLinksHere ]] has no watch button * [[ https://en.wikipedia.org/wiki/Special:WhatLinksHere/Foo | Special:WhatLinksHere/Foo ]] has watch button Expected result: Load the module `mediawiki.page.watch.ajax` only when there is a watch button on the page.
