CJKu has just created a new issue for 
https://github.com/w3c/csswg-drafts:

== [css masing] initial value of mask-repeat and mask-position ==
https://drafts.fxtf.org/css-masking-1/#the-mask-repeat
Name:   mask-repeat
Initial:        no-repeat 
Initial value in blink/webkit: repeat
https://drafts.fxtf.org/css-masking-1/#propdef-mask-position
Name:   mask-position
Initial:        center
Initial value in blink/webkit: 0%

I filed issues onto WebKit Bugzilla & chromium bug tracker to ask them
 following spec. Apple has no action on it[1]. Google changed 
mask-repeat initial value to no-repeat and reverted because of a 
regression on twitter.
Gecko turn on image-mask on nightly/ aurora channel(engineer version).
  Following the spec, we received several regression reports as 
well[3].

So, we either need to persuade all browser vendor schange their 
initial value by what spec defined(and fix all regression on each web 
site), or we probably should  change the spec.

Any thought?
