Disabled arrows problem when particlesToScroll is set

[sohcrana]

Hello,

When I assign a value to the "particlesToScroll" prop and set the "infinite" prop to false, the arrow buttons' disable state doesn't work properly. Additionally, when I try to use the custom arrow slot, the "_disable" class isn't added at all. This issue can be reproduced in the official repl by adding e.g. infinite={false}, particlesToShow={3}, particlesToScroll={2}.

Thank you.
