(It seems there is a margin-top on pre elements that increases the space here which comes from the user default stylesheet). This could be a good rule to add to our normalize stylesheet? cc @Volker_E
This also impacts blockquote elements (see original bug report in T358921)
Software version (skip for WMF-hosted wikis like Wikipedia):
