Custom elements are display:inline by default, so margin-top on the
inner tablist div was not producing visible spacing. Move the margin
to the document-tabs element itself with an inline style (immune to
Tailwind recompile timing) and add class="block" so it participates
in the block flow and the margin takes effect.
