How cross browser is the ping attribute of anchor elements?

Question

is a relatively new, relatively unknown attribute in HTML5\'s anchor element.

How cross-browser compliant is it?

I\'ve looked

Answer 1

You can also see the support with the Wikipedia article Comparison of layout engines (HTML5) for WebKit, Gecko, etc.

It appears to be a potential privacy invasive attribute as well, being able to send data to third parties. It is disabled by default in the browsers that support it.
