What is your source for the "correct" rendering? Are you taking the <br>
elements into account?
http://www.w3.org/TR/html4/struct/text.html#edef-BR :
With respect to bidirectional formatting, the BR element should behave the same
way the [ISO10646] LINE SEPARATOR character behaves in the bidirectional
algorithm.
See http://www.unicode.org/unicode/reports/tr9/ for the bidirectional algorithm.

I'm not talking about <br>. I'm talking about the periods and spaces locaton.
Specailly period and space are different side according to having span or no
tags.
OK, it's simple test case.
<HTML DIR=RTL LANG=AR>
<head>
<Meta charset=UTF-8>
</head>
<body>
<br> This is a testing for BiDi layout without tag.<br>
<span>This is a testing for BiDi layout with span tag.<br></span>
</body>
</html>
You can see each period on different location.

The two periods are in different locations because the first one is part of a
run of neutral characters (since it is a common separator not adjacent to a
number) between two left-to-right characters, and so is resolved to
left-to-right, while the second is part of a run of neutral characters between a
left-to-right character and the end of the paragraph, and so is resolved to the
embedding direction, right-to-left.
Marking INVALID.
To get the same result as in attachment 85857 [details], add a right-to-left mark (‏)
before the <br>.

I've got attachment 85857 [details](above correct result) from IE 5.5. Do you think that
IE 5.5 result is wrong?

Well yes, as a matter of fact I do. I haven't seen the source of IE 5.5, but as
far as I can tell empirically, they treat the <br> element as a paragraph
separator in Bidi processing, which is wrong according to the HTML specification
as quoted in comment 5.
To see that it is the <br> that is creating the effect and not the tags, try
reversing the order of the lines with the span and without the span in your own
example. The rendering is exactly the same.

Simon,
I found similar problem. Please take a look at 151012.
Here is testcase.
<html dir="rtl">
<body>
<input type="CHECKBOX" name="checkbox1" value="check1" checked><B> checkbox1
</B><BR>
<input type="CHECKBOX" name="checkbox2" value="check2" checked><B> checkbox2
</B><P>
</body>
</html>
