Steps to replicate the issue:

• on ptwiki wmf.22 the improved search results display (Search Improvements is enabled by default (along with ruwiki and idwiki)
• got to Special:Search and switch to Dark mode
• perform any search that returns some results e.g. https://pt.wikipedia.org/w/index.php?search=Galaxy&title=Especial%3APesquisar&profile=advanced&fulltext=1&ns0=1

What happens?:

• the search results display on a white background
• the article excerpts are not readable

What should have happened instead?:

• the Dark mode should handle pages (and Special:Search) consistently; the local modifications should be overridden.

Other information:

• the issue happens on ptwiki only due to https://pt.wikipedia.org/wiki/MediaWiki:Common.css
