Toasts from ToastController not showing up with ?ionicMode=wp (Ionic 3)

Using Ionic 3.5.3 the toasts are not showing up if I use ?ionicMode=wp.

For ?ionicMode= ios and md they are working.

Is this normal?

It’s working on which is running on the recent version.

Did you try with a newly created project via ionic start blank blank to repro the problem?
