/*
Disable Vector's `overflow: hidden` because otherwise
our negatively positioned anchor won't be visible.
By itself, showing overflow would cause two problems:
1. We normally hide overflow for a reason. Namely, to ensure
that infoboxes and thumbnails retain their margins and thus
things like heading bottom borders will stay away from the
edge of these floated boxes.
2. Headanchor needs `position: relative`, which affects stacking
context (like z-index). If we don't hide overflow, that means
the heading and its border etc will render over top and
strike-through any content in the thumbnail and infobox.
We solve both of these by bringing back the "create block-formatting
context" behaviour of `overflow: hidden` with `display: flex-root`.
This isn't supported in all Basic browsers, but good enough for
this gadget.
Thanks [[mw:User:Tgr]]!
