Some Fonts Are Bold by Default and Only Need to Meet 3 to 1 Color Contrast when large

Axe is reporting 3 color contrast fails on this page: https://citiqa.mindsmack.com/supportfemalemusic (this URL content may change quickly so I'm also including code snippets).

font-family: "Interstate-Bold";
font-size: 20px;

Axe reports:
Element has insufficient color contrast of 3.16 (foreground color: #ffffff, background color: #ff40b4, font size: 15.0pt (20px), font weight: normal). Expected contrast ratio of 4.5:1

WCAG 2.x glossary definition: large scale (text) with at least 18 point or 14 point bold or font size that would yield equivalent size for Chinese, Japanese and Korean (CJK) fonts

Expectation: Interstate-Bold at 15.0 pt(20px) only needs to meet 3 to 1 because the FONT is bold itself.

Actual: Axe is inaccurately reporting a WCAG 2.x failure of 1.4.3

Motivation: Please account for fonts that are bold by default..and do not fail this.
