Hi there - just a little clarification of my own -
Much as with the inline-edit "special characters" family of issues, when I mean to say
that this is a "technical issue" I don't specifically mean "this is a technical issue 
which we can't think how to resolve" but "this is an issue which has a technical 
origin, but whose fixes have costs whose implications are too awful to contemplate" :)

I hate to sound like a "developer who meddles in usability" but from what I can see,
the issues of a widget whose presence changes the absolute size of the viewport 
unexpectedly, or still worse, causes scrollbars to appear which the user would have
to manipulate to successfully use the control (or worse still causes the viewport to
jump) is a usability nightmare. The unexpected appearance of spurious scrollbars is,
for example, one of the more serious beefs we have against iframes. 
"Am I wrong?"
