Avoid hidden tab when the Keyboard is open(IONIC v4)

Hey, I am working with ionic 4, and when the keyboard is open, ion-tab-bar’s are added a css clas tab-bar-hidden and as a result my tab-bar dissapears while the keyboard is open. Why is this working like that?

I do not understand why a class is added to hide the tab-bars, that should not work like that. :face_with_raised_eyebrow:
