Tween alpha problem in 1.20

Hello,
recently I've updated one tour from 1.16.6 to 1.20 and I've found that this script doesn't work properly anymore.
The hotspot doesn't fade out.

tween(hotspot[%1].alpha, 0.0, 0.5, default);
tween(hotspot[%1].rotate, %6, 0.5, default);
tween(hotspot[%1].ath, %4, 0.5, default);
tween(hotspot[%1].atv, %5, 0.5, default, WAIT);

I have to change it to

tween(hotspot[%1].rotate, %6, 0.5, default);
tween(hotspot[%1].ath, %4, 0.5, default);
tween(hotspot[%1].atv, %5, 0.5, default, WAIT);
tween(hotspot[%1].alpha, 0.0, 0.5, default);

But then the hotspot fades out when it stops moving.
I want it to begin to fade out just after the click.

Is it possible to fix it?

I've found that without this code it gets fixed:

onover="tween(alpha,1)" onout="tween(alpha,0.6)"

but how to keep the onover and onout actions without interrupting the fading out of clicked arrows?
