TimelineMax call with repeat and delays appears to fire twice

I've been staring at this for too long, some maybe I just need a second set of eyeballs on this.

I really thought this single line of code should fire once every 3 seconds (after the initial 6 second wait period).

But it appears to be firing twice at the same time after the first solo-fire. I must have some flawed understanding of how repeat + repeatDelay + delay works.

 

I was expecting:

nothing for first 6 seconds

call function and log some text with random number

wait 3 seconds

call function and log some text with random number

wait 3 seconds

call function and log some text with random number

wait 3 seconds

etc... 

new TimelineMax({repeat:-1, repeatDelay:3, delay:6}).call(func);

Nah, you just created a really awkward scenario where you've got a zero-duration timeline and a callback at the VERY beginning. I'll spare you the lengthy explanation, but here's a much better setup: 

 

new TimelineMax({repeat:-1, delay:3}).add(func, 3);

 

Or:

new TimelineMax({repeat:-1, delay:3}).call(func, null, null, 3);

 

Or:

new TimelineMax({repeat:-1, onRepeat:func, delay:3}).to({}, 3, {});

 

Or:

new TimelineMax({repeat:-1, onRepeat:func, delay:3}).set({}, {}, 3);

 

(I could go on with more options, but you get the idea) :)
