Description

The columns 'is-variable' class with the different column gap class modifiers are not working. Neither on the document page (https://bulma.io/documentation/columns/gap/).

I can confirm the behaviour.

I have tracked this down to

bulma/sass/grid/_index.scss

Line 4 in 72e99d1

@forward "columns";

This line imports columns.scss, however the is-variable stuff is in columns-v2.scss.
