   …ions (bug 1780375)
   
   This patch doesn't structurally change the text layer: it just adds some aria-owns
   attributes to some spans.
   The aria-owns attribute expect to have an element id, hence it's why it adds back an
   id on the element rendering an annotation, but this id is built in using crypto.randomUUID
   to avoid any potential issues with the hash in the url.
   The elements in the annotation layer are moved into the DOM in order to have them in the
   same "order" as they visually are.
   The overall goal is to help screen readers to present to the user the annotations as
   they visually are and as they come in the text flow.
   It is clearly not perfect, but it should improve readability for some people with visual
   disabilities.
