This bug happens in Mozilla 1.5a
but WFM in trunk 2003082522 linux.
Nesting iframes stops at 3rd level.

Confirmed on WinXP SP1 trunk 2003082505.

Is Browser/Layout: HTML Frames the right component ?

On second thought, I'm not sure this is a bug at all.
<a href="#"> means 'top of current page', and so the iframes do have the right
behavior.

The only bug here, is that it 'only' copies it three levels deep. But that must
be some check in order to not enter an infinite loop.

So if noone objects, I will resolve as INVALID (Not a bug).

I agree. See bugs 98158 and 136580 about preventing infinite (i)frame recursion.
