Repeater Animation Hover Lag

Question:
I created a custom hover/color animation on hover for text in a repeater. Can anyone advise me why the first item animation in the repeater lags behind the rest of the items by a full second?

Is this a bug? Has anyone else experienced this?

Yes, i think i have already seen such buggy behaviour.
This also happens with functions like →

hide() + collapse()
show() + epand() …
…related to the repeater.

In most cases i could fix such bugs by using…

await $('#myElementID').hide('fade');
$('#myElementID').collapse();

Is this a similar example of what you are trying to describe ?
