`multitext` always has `Pre` format

When using multitext for translations (reporter/Autolib/Reporter/Stack/Type.hs), The text behaves rendered on webpages as if the text was using the Pre constructor even if explicitly using Doc constructor of Output (output/Autolib/Output/Type.hs). E.g. here: image the former has no translations and is created as Doc directly, while the latter is using Doc in combination with multitext.
