[Accessibility] ion-input tabindex cross-browser difference

Bug Report

Current behavior: Desktop: Firefox (latest update on MacOS 10.14.3) - tabindex on ion-input not supporting tab-into. Tab key from first ion-input goes directly to the browser location bar. Chrome and Safari - tabindex on ion-input “works” but it highlights the <ion-input> markup element first, then must tab again to focus into the contained .

Mobile web - iOS Safari, Chrome, FF - no indication that tabindex is respected. Usually browser will enable up/down arrows indicating navigation to the next input.

Expected behavior: Desktop users want the tab key to move from input to next input directly (or next tabindex element in the flow), within a Form entry experience, enabling quick data entry as the highest priority. The Firefox issue denies any use of the Tab key, must mouse-click to next input.

Steps to reproduce: Setup a form with ion-input with tabindex values, and test in multiple browsers on desktop and mobile(web).

      <ion-item-group>
        <ion-item>
          <ion-label position="floating">*Name</ion-label>
          <ion-input name="name" required="true" tabindex="1"></ion-input>
        </ion-item>
  
        <ion-item>
          <ion-label position="floating" >*Email</ion-label>
          <ion-input name="email" inputmode="email" type="email" required="true" tabindex="2"></ion-input>
        </ion-item>
      </ion-item-group>
