How can I change size of dropdown arrow and loader spinner?

[scramatte]

Hi,

How can I change size of dropdown arrow and loader spinner?
I've tried to set following variables

--vs-controls-size: 0.75;
--vs-controls--spinner-size: 0.75;

If I override styles vs__spinner , I've been able to reduce size of the spinner but I loose animation:

.vs__spinner {
          transform: scale(var(--vs-controls-size)) !important
}

Note that without word "!important" the style is not applied.

I'm unable to get it working properly
Can you give me an hand?

Regards
