Describe the bug
Changing --datepicker-spacing custom css variable does not work, calendar layout does not change.

To Reproduce
Try to use:

<style>
	:global(.datepicker[data-picker-theme='custom-datepicker']) {
		--datepicker-spacing: 3px;
		--datepicker-container-left: -400px;
		--datepicker-calendar-day-width: 26px;
		--datepicker-calendar-day-height: 26px;
		--datepicker-calendar-width: 240px;
		--datepicker-calendar-header-text-font-size: 0.9rem;
	}
</style>

All values are changed and calendar changes according to them except --datepicker-spacing. Even if this value is the only one I let in the custom them.

Expected behavior
The calendar padding should change according to calculated values.

When I try to change the value of --datepicker-spacing in browser inspection tools, it works. Both Safari and Chrome.
