Bug Report

Ion-Textarea inside a normal form ... with previous inputs ...

      <!-- Email -->
      <ion-item>
        <ion-label position="floating"
          >Email
        </ion-label>
        <ion-input
          aria-required="true"
          formControlName="email"
          name="email"
          type="email"
          clearInput
          required
        ></ion-input>
      </ion-item>

      <!-- Subject -->
      <ion-item>
        <ion-label position="floating"
          >Subject
        </ion-label>
        <ion-textarea
          aria-required="true"
          auto-grow="true"
          formControlName="subject"
          type="text"
        ></ion-textarea>
      </ion-item>

Generates id="ion-input-0-lbl"
<ion-label _ngcontent-sah-c4="" position="floating" ng-reflect-position="floating" class="sc-ion-label-md-h sc-ion-label-md-s md label-floating hydrated" id="ion-input-0-lbl">Subject</ion-label>

Which duplicates previous ion-input ID.
This causes Lighthouse Audit an issue of Accessibility: [id] attributes on the page are not unique

Also HTML gerated tag textarea misses the aria-labelledby attribute to mach respective label.
<textarea class="native-textarea sc-ion-textarea-md" autocapitalize="none" name="subject" placeholder="" style="height: 53px;"></textarea>

This causes Lighthouse Audit another issue of Accessibility: Form elements do not have associated labels
Failing Element > textarea.native-textarea.sc-ion-textarea-md

Ionic version:

[x] 5

Current behavior:

ion-label#ion-input-0-lbl

Expected behavior:

Other ID attribute must be set, like ion-label#ion-textarea-0-lbl
Textarea HTML tag must also include this label: ion-textarea-0-lbl
<textarea **aria-labelledby="ion-textarea-0-lbl"** class="native-textarea sc-ion-textarea-md" autocapitalize="none" name="subject" placeholder="" style="height: 53px;"></textarea>
