Ionic 4 RC - Huge fab button when routerLink directive is used

[Axdron]

Bug Report

Ionic version:

[x] 4.x

Current behavior:
When using the routerLink directive in a fab-button, it became huge in the screen. Without the directive, it's ok.

Expected behavior:
I expect the button having the same size with or without the routerLink directive.

Steps to reproduce:

Related code:
The huge button code:
<ion-fab-button [routerLink]="'/categorias'" color="success">

The normal button code:
<ion-fab-button (click)='true' color="success">

This problem exists also in beta 19.
If single fab button is used, as a workaround put [routerLink] in <ion-fab> instead of <ion-fab-button> then it looks like it should
