As a data point, this is exactly what gmail does for all of its email and
chat notifications currently - it analyses the text being displayed, and
inserts RLE/LRE formatting chars if needed. This is important since the
title and body may have differing directions depending on the content of
the email, and their directions may not match the directionality of the
parent document. It's possible that this might no longer be required if we
aren't inheriting directionality from the parent document as you suggest,
assuming we can properly rely on the browser to determine this for us
(treating the title and body as separate paragraphs that may need different
directionality).
