I am developing inside of a Google Chrome Extension. In this environment, I have the ability to inject JavaScript into third-party websites after requesting the appropriate permissions. As such, I am injecting code into an iframe referencing a cross-domain resource, but am not bound by the same cross-origin security policies as would be expected in a ‘normal’ environment.<\/p>\n

The code I am executing inside of this iframe is:<\/p>\n

var requestId = window.requestAnimationFrame(function(){\n    console.log(\"Success\");\n});\nconsole.log(\"Request Id:\", requestId);\n<\/code><\/pre>\n
After this code is executed, my output looks like:<\/p>\n
\n
Request Id: 1<\/p>\n<\/blockquote>\n
The callback of requestAnimationFrame is never executed. requestAnimationFrame is defined. The callback works fine if I use a non-optimized call such as setInterval.<\/p>\n
The callback is executed properly outside of the iframe<\/strong> but no security errors are shown in my console when it fails inside of the iframe. This is only for the latest version of Google Chrome — do not worry about other implementations of requestAnimationFrame.<\/p>\n
Are there any steps I can take to debug this issue? window.requestAnimationFrame trails off into native code and my requestId is valid… so I’m at a bit of a loss.<\/p>\n
