[css-compositing] Isolation groups

Hi,

I have a few questions about the spec:

Section 3.3: I don't understand how blending creates an isolation group.
If I set 'mix-mode-blend' on a circle and the circle gets blended with
the background, what is the isolation group? An example would really
help.

Example 4: It appears that the three circles are being blended in one
isolation group and then put over the gray background. What is causing
the circles to be isolated? If the SVG is referenced from an <img> then
it should be isolated but if it is included inline then it should not
be(?). If I try the SVG in Chrome the circles are never isolated, no
matter what I do (stand-alone SVG, external SVG, inline). Is this due to
a lack of isolation support in Chrome?

Example 4: Minor quibble: The green color depicted is 'lime', not
'green'.

Also, example numbering skips numbers.
