F47, "Failure of Success Criterion 2.2.2 due to using the blink element", starts with:

The blink element, while not part of the official HTML or XHTML specification, is supported by many user agents.

Checking with current builds of Edge, Safari, and Firefox (warning: contains blinking), the HTML blink element isn't supported.

We could re-purpose it to be about CSS blinking or we could just delete it.

i'd say just remove it, and create a new failure (rather than repurposing)

As an update to this, as I've just stumbled on it after a few months, Chromium, Firefox, and Safari all don't support text-decoration:blink either.

I'll work on this issue next.

Replace f4 and f47 (#4166)
8267b59 
Closes #3823 

[F4](https://www.w3.org/WAI/WCAG22/Techniques/failures/F4.html) and
[F47](https://www.w3.org/WAI/WCAG22/Techniques/failures/F4.html) should
be replaced. CSS' `text-decoration:blink` is deprecated and has no
modern browser support, and the HTML `blink` element is obsolete.

[This new failure
technique](https://deploy-preview-4166--wcag2.netlify.app/techniques/failures/failure-of-222-due-to-blinking.html)
replaces those two techniques.
