Debugging Javascript: console.log shows only first parameter in Console Toolbar

I  use console.log( a, b ,c ) to debug javacript.

But PHPStorm console toolbar shows only the value of 'a' ( the first parameter )

since i usually log method calls like console.log( 'methodname', param_1 , param_2, param_3... ) this isn't very helpful.

is there a configuration for that?? thanks!
