Valid Autocomplete Values (valid-values)
Check that autocomplete values are from the W3C-approved list and do not contain typos or non-standard values.
Comma-separated autocomplete tokens:
This input uses autocomplete="work,email". While work and email are valid tokens individually, separating them with a comma instead of whitespace makes the value invalid. The browser cannot interpret it correctly, which fails WCAG 1.3.5.
