Filter the HTML element the Button block falls back to when the block itself does not specify one. Jetpack Forms uses this to default its submit button to `button` while a form renders, since an `a` inside a form can never submit it. Values outside ‘a’, ‘button’ and ‘input’ are ignored by the render callback.
Parameters
- $element
string The default element. One of 'a', 'button', or 'input'.
Changelog
- Introduced in Jetpack 16.2
