but blank grey for the rest. The content resizes horizontally as designed, but
only the area initially drawn gets redrawn. 


Reproducible: Always

2.find example 4.8.1
3.click on "view"

Actual Results:  
Page rendered partially (only thin strip at top)

Expected Results:  
Rendered entire page.

Only tried on a dual processor (300mhz each) machine.

#disclaimer: Don't know XUL. Could meaning of page have changed ?

Yes, it looks at though the meaning of the page has changed. The IFRAME has
'height="20"'.

originally:
 "For XUL box elements, the attributes width, height, minwidth, minheight,
maxwidth, and maxheight can all be used to specify sizes. Their possible values
correspond to the allowed values of their corresponding CSS properties.".
but now:
 "The height of the iframe in pixels. It is recommended to use the CSS height
property instead".

As "20" is not a valid css height, I suspect the example previously defaulted to
100px, but now is interpreted as 20px.

Mostly not a bug, then.
