One per frame last item breaks depending on OS about sly HOT 1 OPEN

I implemented item based horizontal basic and have the same issue. It does appear on some screen sizes but not on others, I can't find any pattern in that behaviour.

I think it is a rounding problem. When I wait for all elements to render and then reduce say the margin of the last element by 1px it fits into the first line again.

This fixed it for now (the margin here is 0.25rem smaller than normal):
$( '.class' ).last().css( 'margin', '0 1rem 0 0' );

This goes right after inits and reloads:
sly.init();
sly.reload();

EDIT:

The solution above did not work all the time because the rounding seems to happen on each element not on their sum, so the more elements there are, the more rounding happens. Instead I now calculate the width of each element including comma values and round it up, and then resize the parent (aka slidee).

var totalWidth = 0;
var elementWidth = 0
var elementMargin = 0;
slyElement.each( function() {
  elementWidth = Math.ceil( $( this )[0].getBoundingClientRect().width );
  elementMargin = parseInt( $( this ).css( 'margin-right' ) );
  totalWidth = totalWidth + elementWidth + elementMargin;
} );
slySlidee.width( totalWidth );
