Fix loading spinner's position

[DrDreave]

Reproduction Link

Vue Multiselect

Steps to reproduce

1. Trigger loading state in asynchronous select

Expected behaviour

The loading spinner should be positioned the same way as the dropdown arrow so there is a smooth transition between both states.

Actual behaviour

There is an offset between the spinner and the arrow.

Proposed fix

.multiselect__spinner {
  /* Same values as for .multiselect__select */
  width: 40px;
  height: 38px;
}

I tried contributing to the development of OSS. Is there something wrong with my fix?

@kenji7157 Hey! I assume there’s nothing wrong with it. The only issue is that master is now pretty unstable, which prevents me from testing and building a new release.
