Sass ABS deprecation warning for bootstrap-rubygem v 5.3.1

A recent update of the sass-embedded gem causes a deprecation warning when compiling assets:

DEPRECATION WARNING: Passing percentage units to the global abs() function is deprecated.
12:40:48 css.1   | In the future, this will emit a CSS abs() function to be resolved by the browser.
12:40:48 css.1   | To preserve current behavior: math.abs(100%)
12:40:48 css.1   | To emit a CSS abs() now: abs(#{100%})
12:40:48 css.1   | More info: https://sass-lang.com/d/abs-percent

The warning traces to bootstrap/vendor/_rfs.scss line 57, through the Bootstrap grid files, and is surfaced from app/assets/stylesheets/application.scss line 60. Start by reproducing asset compilation and inspecting that call in the reported dependency; done means the deprecation warning no longer appears during compilation.
