See https://gerrit.wikimedia.org/r/#/c/79341/ Parsoid currently treats tabs like spaces when it comes to indent-pres.
http://parsoid.wmflabs.org/pl/Wikipedia:Strona_g%C5%82%C3%B3wna does look somewhat preformatted. Too bad that this inconsistency is exploited. Would be tempting to fix it otherwise.
I doubt it's exploited widely, but it does sometimes make the code cleaner when using complicated markup, such as on that main page. Removing the tabs there would be easy and I can do that; I remember being surprised that this worked when I wrote it. We should get some stats, but I'd be surprised if it affects any other page on any wiki.
