hi, something that annoying me (and a lot people that working in rtl wikis in wikipedia) is that why firefox do not calculate bidi algorithm for each separate?

comapre this data:text/html;charset=utf-8,%3Ctextarea%3E%D8%B4%0A==%D8%B4==%3C/textarea%3E%3Ctextarea%3E%0A%0A==%D8%B4==%3C/textarea%3E on Google Chrome, Konqueror, Internet Explorer with Firefox ...

you can see that they calculate bidi algorithm for each line separate.

i can not find here http://unicode.org/reports/tr9/ a note that prevent this.

also read this (that i found from that document) i '''think''' this is related to this bug

* Reordering. The text within each paragraph is reordered for display: first, the text in the paragraph is broken into lines, then the resolved embedding levels are used to reorder the text of each line for display.


Reproducible: Always

The problem with newlines in preformatted text is that it's not clear that they're paragraph separators...

That said, I think Simon landed a change to treat them as such today.

nice, working well, thank you, but i can see something same delayed updating can seen on firefox nightly builds when editing on wikipedia rtl pages (that is not available on ltr pages), watch this:
http://fa.wikipedia.org/w/index.php?title=%DB%B2%DB%B7_%D9%81%D8%B1%D9%88%D8%B1%D8%AF%DB%8C%D9%86&action=edit
please insert two or more enter on middle lines of it and delete them.
or in this page:
http://he.wikipedia.org/w/index.php?title=18_%D7%91%D7%99%D7%95%D7%9C%D7%99&action=edit
before this line: ==נולדו== please insert enter;
i think it can reported as a separate bug but i can not provide better example to show that.

I think that's bug 645119, which I just filed (and it's probably my fault -- it doesn't have anything to do with bidi).

Attachment: patch 2 - Use -moz-appearance:none to work around unreliable Gtk3 theming of textarea

And the same applies here, too; the failures often seem to show up together.

Ugh, bzexport misunderstood me and attached this to the wrong bug. Will re-post it on bug 1237355.
