I reported a
similar bug to Adobe a month ago, which involves parentheses and <br>.
It looks like this:

Code:
<body>
<p>
With opening parentheses<br />
(a long line [...]
</p>
<p>
Without opening parentheses<br />
a long line [...]
</p>
</body>
They already fixed the bug before the report, and it is available in the latest SDK.
Of course, that isn't worth much until Sony and others update their firmware.
