fix: Transition fill mode fix 9741

[adiguba]

Fix issue #9741

CSS transition are created with fill:'both', which maintains the state of the transition on the element, even after the animation ends.

I just removed it to use the default behavior (fill:'none')

I believe we tried this and this caused issues when trying to apply multiple transitions to an element at the same time (fade and fly for example). It might be better that we stop the animation rather than pause it instead.

I tested with cancel() instead of pause() on the onfinish handler, and it seem to work for CSS transition.

But with JS transition but it produce an incorrect tick with 0 before the final tick with one.

A JS transition like this :

	tick: (t) => {
		console.log(t);
	}

will produce something like this :

0
0.1
0.2
0.3
0.4
0.5
0.6
0.7
0.8
0.9
0.9
0
1

And I don't understand why there is a pause() inside onfinish()
