Ruby sass sometimes changes single to double quotes

[eevee]

This is left alone:

p { content: ''; }

But this:

$a: 'hi';
p { content: '#{$a}'; }

Becomes this:

p {
  content: "hi"; }

This might only happen when #{} is involved, but I'm not positive.

There's no semantic difference in CSS, and arguably this is a Sass bug, but this ticket serves as documentation.
