    Add workarounds for postcss values parser error · b8880e5e
    Geremia Taglialatela authored 
    postcss-values-parser returns a syntax error when a negative value is
provided in a `calc` function after a CSS variable.

This is not an issue with Bootstrap itself, but a workaround to allow
projects using postcss-values-parser to keep upgrading and compiling
bootstrap

Ref: shellscape/postcss-values-parser#138, twbs/bootstrap#35033

Fix: #36851
