Comment:This is a part of the proposals made by the "Additional Requirements
for Bidi in HTML" W3C First Public Working Draft. For a full description of the
use cases, please see 
http://www.w3.org/International/docs/html-bidi-requirements/#newline-as-separator
[http://www.w3.org/International/docs/html-bidi-requirements/#newline-as-separator]
. Here is the proposal made there:

In elements where line breaks are not collapsed, e.g. <textarea> and elements
with white-space:pre|pre-line|pre-wrap, the LINE SEPARATOR (U+2028) and
PARAGRAPH SEPARATOR (U+2029) characters should also break lines. PARAGRAPH
SEPARATOR characters in these elements should constitute UBA paragraph breaks,
while LINE SEPARATOR characters should constitute UBA whitespace.

When PARAGRAPH SEPARATOR introduces a UBA paragraph break, the base direction
of the new UBA paragraph will be determined by the computed direction of the
nearest ancestor element whose bidi properties require its contents to be in a
separate UBA paragraph (or sequence of paragraphs), e.g. a block element or an
element directionally isolated by the ubi attribute (which is being proposed in
a separate bug). Furthermore, for every element on the path in between that
results in the creation of an embedding or override level, e.g. a <bdo> element
or any element with a dir attribute or a value other than "normal" for the
unicode-bidi CSS property, the correspondeng embedding or override level is
re-introduced at the start of the new UBA paragraph (to be closed at the end of
the element or the UBA paragraph, whichever comes first).
