bug: "Next" keyboard button does not focus on correct field.

# Bug Report

**Ionic version:**
[x] **4.10.0**

**Current behavior:**
When I click the "next" button on the keyboard, the focus goes to the next "ion-input" field, even though I previously had an "ion-select" field.

**Expected behavior:**
When you click the "next" button the focus should go to the next "ion-item" of the form.

**Steps to reproduce:**
Start a new project
On a page, put the code below
