Maximum stylus call stack size exceeded when using `display: flex` about stylus HOT 2 OPEN

Stepping through it seems it gets stuck in an infinite loop...

it's hitting the "else" step of this:
https://github.com/stylus/stylus/blob/dev/lib/functions/index.styl#L266

stylus/lib/functions/index.styl:262
add-property-function = add-property
add-property(name, expr)
  if mixin
    {name} expr
  else
    add-property-function(name, expr)

Seems like if mixin is missing, it just calls itself over and over again. Maybe a race condition in how nib initializes the mixin?

Looking at how we get into this situation, I see it first going into display(flex) here:
https://github.com/stylus/nib/blob/fb3c70cfaac29f4d6efa8d568c29e20ba2dcd42d/lib/nib/flex.styl#L16

We then encounter add-property here:
https://github.com/stylus/nib/blob/main/lib/nib/vendor.styl#L53

And then get into the infinite loop.
