Description Andreas Tolfsen 2014-09-02 05:38:16 UTC 
The x/y/height/width properties of ElementRect are defined as doubles [1].  Since pixels are defined in the CSS 3 Values specification as of the type NUMBER [2] we should make sure to use a JSON compatible data type, number [3].

Possibly this bug is a covered by bug 26275.

This is because it is described as WebIDL currently. WebIDL does not have a number type.

Comment 3 Andrey Botalov 2014-09-06 06:58:37 UTC 
Actually switching to JSON won't be fully compatible with CSS Values spec as it says the following about Number type:
> As with integers, the first character of a number may be immediately preceded by ‘-’ or ‘+’ to indicate the number's sign.

RFC4627 doesn't seem to allow for a number to start from "+"
