   Tables and sections are breakable by default, but do not provide automatic anchor and caption orphan prevention.
  -For tables, that means the anchor and caption can be left on the current page if the table is advanced to the next page.
  +For tables, that means the anchor and caption could be left on the current page if the table gets pushed to the next page.
   For sections, that means the section's title may be left on the current page if the first content block doesn't fit.
   However, you can turn on orphan prevention for tables and sections by adding the (seemingly redundant) `breakable` option as a hint.

negative.code: :description: By default, most blocks are breakable with anchor and caption orphan prevention. The unbreakable option prevents a block from breaking across pages.
  
  Asciidoctor PDF gives the author some control over where content blocks are placed using the `unbreakable` and `breakable` options, and tries to provide sensible defaults when these options are not used.
  
  If you want a block to be truly unbreakable, you add the `unbreakable` option.
  If you want to prevent the orphaning of the anchor and title of a table or section, then you add the `breakable` option.
  Otherwise, you don't need to specify either of these options.
  This page goes into detail about what functionality these options enable.
