Inherit specific `font` properties, not all
Inherit specific `font` properties, not all

Following-up I90078ee8073ede5584cbcd04c23cabbf4be595e6 it's better
to inherit only specifically needed `font-*` properties instead of
all that belong to `font` shorthand. As example `line-height` gets
overwritten in the very next line. We're already doing specific
inheritance at `.theme-oo-ui-textInputWidget` in MediaWiki theme.
