Multiselect is crashing when using groups and $isDisabled

[sagg]

Hi there,
i'm using grouped options and in case i provide $isDisabled: true in an option there is an error thrown in the console.

If i'm correct this should work? I only found this comment to disabled options:
#176 (comment)

Thanks a lot!

Reproduction Link

(The shown example is a copy from the docs, i only added $isDisabled: https://vue-multiselect.js.org/#sub-option-groups)

Steps to reproduce

Setting $isDisabled when using groups.
Remove $isDisabled from the example and everything is working fine.

Expected behaviour

VueMultiselect should appear.

Actual behaviour

Error is thrown in the console.
