[0.9.4] Sass deprecation warning

[robtree]

Overview of the problem

I'm using Bulma version 0.9.4
This is a Sass issue: I'm using version 1.77.8

Description

#3856 fixed this issue for Bulma v1, but many Bulma users may not be able to upgrade to Bulma v1 due to difficulties with migration, eg. #3867.

Deprecation Warning: Sass's behavior for declarations that appear after nested
rules will be changing to match the behavior specified by CSS in an upcoming
version. To keep the existing behavior, move the declaration above the nested
rule. To opt into the new behavior, wrap the declaration in `& {}`.
