[BUG] -o-… and -moz-… not added to CSS

Hi Sebastian,

I have added a selector and in Transition enabled the timing function “ease-in-out”. The following has been added to the generated CSS:

#mysticky-nav.wrapfixed {
	-webkit-transition-timing-function: ease-in-out;
	transition-timing-function: ease-in-out;
}

Why are the -o- and -moz- properties are not added as well?

When I show the generated CSS there is a warning sign on the left that says:

The property -o-transition-timing-function is compatible with -webkit-transition-timing-function and should be included as well.
The property -moz-transition-timing-function is compatible with -webkit-transition-timing-function and should be included as well.

Could you please check?

Thank you.
