Usage with sass v1.65 breaks due to usage of rem(...)

[jafin]

Running sass 1.65 changelog against the qg-main.scss web-template will result in errors with usage of function rem (expecting 2 parameters, got 1)

For Example:
https://github.com/qld-gov-au/web-template-release/blob/master/scss/scss-general/bootstrap/_variables.scss

$h1-font-size:                rem(25px) !default;
$h2-font-size:                rem(20px);
$h3-font-size:                rem(18px) !default;
$h4-font-size:                $font-size-base !default;
$h5-font-size:                rem(12px) !default;
$h6-font-size:                rem(11px) !default;

Repo Steps

Execute sass (dart-sass) against qg-main.scss
npx sass qg-main.scss
Note errors on output.

There is a function defined as rem in css/scss-general/bootstrap/_rem.scss, perhaps this is not overwriting the sass internal rem in the new version?

Workaround

revert to sass 1.64
