Cannot add a border to fab-button

[Maistho]

Bug Report

Ionic version:

[x] 4.x

Current behavior:
Cannot add a border or change the border-radius of fab-button

Expected behavior:
Can add a border or change the border-radius, as the documentation states is possible.

Steps to reproduce:

ion-fab-button {
  --border-radius: 10px;
  --border-color: white;
  --border-width: 4px;
  --border-style: solid;
}

Related code:
This line sets border to be zero, not taking the custom properties in account: https://github.com/ionic-team/ionic/blob/master/core/src/components/fab-button/fab-button.scss#L94

Thanks for your issue! You are right, the CSS variables are in the documentation, but not integrated yet. I think this is something for @brandyscarney :)

If that's OK, I can open a PR in order to get this fixed sooner. Already have it fixed on my fork. 🙂

That would be the best way :)
