labelMdFontWeight is adding 200 to the value selected

[famonfa]

I’ve encountered a bug with the labelMdFontWeight appearance variable in the Stripe Connect embedded components. No matter what value I set, the computed CSS font-weight is always 200 more than the value I provide.

Steps to Reproduce

Set up a minimal reproducible example (see sandbox link below).
Set labelMdFontWeight to "400" in the appearance variables.
Inspect the rendered label in the Stripe Connect component.

Expected Behavior

If I set labelMdFontWeight: "400", the computed CSS should be font-weight: 400.

Actual Behavior

If I set labelMdFontWeight: "400", the computed CSS is font-weight: 600.
If I set labelMdFontWeight: "100", the computed CSS is font-weight: 300.
If I set labelMdFontWeight: "500", the computed CSS is font-weight: 700.
It appears that the value is always offset by +200.

labelMdFontWeight is 400. Computed 600
