Missing --bulma-column-gap CSS variable when importing columns SCSS module into class

[FilipJakab]

Overview of the problem

This is about the Bulma CSS framework

I'm using Bulma version [1.0.1]

I am sure this issue is not a duplicate?

Description

When importing columns module I do not have --bulma-column-gap CSS variable defined

Steps to Reproduce

1. Import columns module scoped to some class:
   
2. Use simple columns:

<div class="columns">
	<div class="column is-4-desktop">
		Smaller column
	</div>
	<div class="column">
		Big column
	</div>
</div>

3. Check computed width of fixed column:
   

Expected behavior

The variable --bulma-column-gap should get set.

Actual behavior

The reason is that the --bulma-column-gap variable is missing, so the width does not get set.
By setting the variable manually, the columns start to work.

Do I have to import anything else? Is it the limitation of scoped imports?

Thanks
