I whipped up a quick uBO rule to fix that (also makes meta-information lines readable):

    thefrontpage.dev##p.newspaper-copy:style(line-height: normal !important; font-size: 1rem !important;)
    thefrontpage.dev##p.article-meta:style(font-size: 1rem !important; font-weight: normal !important; letter-spacing: normal !important;)

EDIT: changed to 1rem as someone else suggested
