Bug? VS.NET 2003 and styles using 'expression'

[Neil Moss]

Hi,

I've got a repeatable nasty in my VS.NET 2003 IDE (running on WinXP Pro
SP1).

For an ASPX web form, in HTML mode, declare an element with a style
attribute that includes an expression e.g.

<div style="width:expression(document.body.clientWidth-100)">
Hello world.
</div>

Switch to Design mode. Make a change (e.g. type a space at the end of the
form). Switch back to HTML mode.

The style attribute is erased. Completely. Silently.

That can't be right, can it? Can anyone else repeat this?
Regards,
Neil Moss.
