Update to 3.5.3 and not work menuToggle

#1

I have updated ionic version 3.5.3 and sidemenu has stopped working, no error appears in console
this is my html:
<ion-header> <ion-navbar> <button ion-button menuToggle> <ion-icon name="menu"></ion-icon> </button> <ion-title>Home</ion-title> </ion-navbar> </ion-header>

Create a new project with the sidemenu starter (ionic start on the command line) and see if it works there. If it does (it will) compare to what you have.
