Table.configure had renderWrapper unset (defaults to false), so tables
rendered as bare <table> elements with no .tableWrapper div. The
overflow-x: auto rule in prose.css targets .tableWrapper and never
matched, so a wide table pushed the horizontal scrollbar onto the
issue detail's page-level scroll container instead of scrolling
within the table itself.
