Wow, I have waited 3 years for this. There was support for 
background-size in a background shorthand in IE9 preview but then it 
went bye bye from IE9 beta.


Below is a reference image (screenshot) of the above test that I took 
while I had IE9 preview before it disappeared from my machine (don't 
know how).


What really concerns me about this is that all implementations have to 
get SVGs (especially those with no intrinsic size, ratio or dimension) 
right before implementing background-size in a background shorthand. 
This also applies to gradients (take repeating-linear-gradient as one 

I do note that background-position is different with for SVG with no 
intrinsic size in WebKit compared to Firefox, Opera and IE9+. The forth 
example 'Test 4' in the below test shows this.
