Custom Actions with Tel Not Displayed

[butchewing]

I am wanting to add a custom action for a tel link. It does not display on Tel links but does on Mailto links.

This works

<a href="mailto:[email protected]" data-custom-action-text="Open Docs" data-custom-action-url="https://mailgo.dev/docs/">[email protected]</a>

This does not

<a href="tel:+1234567890" data-custom-action-text="Open Docs" data-custom-action-url="https://mailgo.dev/docs/">[email protected]</a>
