No meta refresh delay (no-meta-refresh-delay)
The <meta http-equiv="refresh"> element must not include a delay value before redirection or refresh.
Redirect with invalid meta:
This page includes two <meta http-equiv="refresh"> elements. The first one is syntactically invalid and ignored by browsers because it uses colon (":") rather than semicolon (";"). The second one performs a timed redirect after 5 seconds without user control, which fails WCAG 2.2.1.
