When U+00B7 MIDDLE DOT is included in text mode, KaTeX complains about \cdotp being undefined.

(La)TeX code:

a = \text{c·}

Expected behavior:
The equation should render as ‘a = c·’, as in this screenshot (from QuickLaTeX):

Environment:

• KaTeX Version: 0.15.6 (both in the demo and with a locally installed copy)
• Device: Desktop
• OS: Linux
• Browser: Firefox
• Version: 100.0.2
