FloatingLabels not working for input date or input time

Describe the issue

Unfortunately floatingLabels are not working on input date or input time fields.

Visually they look like a floatingLabel with a value already selected.

While there is no value selected, it is impossible for the user to determine, if the value 12:30 is a actual value or a placeholder.

Using Safari on OS X.

Thank you!

Reduced test cases

I am using React Bootstrap:

<Form.Group>
  <InputGroup>
    <FloatingLabel controlId="openingHours" label="Opening">
      <Form.Control className="left-icon icon-opened" type='time' placeholder='Test123' />
    </FloatingLabel>
    <FloatingLabel controlId="openingHours" label="Closing">
      <Form.Control className="left-icon icon-closed" type='time' placeholder='Test123' />
    </FloatingLabel>
  </InputGroup>
</Form.Group>

Producing this html:

<div>
  <div class="input-group">
    <div class="form-floating">
      <input placeholder="Test123" type="time" id="openingHours" class="left-icon icon-opened form-control">
    <label for="openingHours">Opening</label>
  </div>
  <div class="form-floating">
    <input placeholder="Test123" type="time" id="openingHours" class="left-icon icon-closed form-control">
      <label for="openingHours">Closing</label>
    </div>
  </div>
</div>

What operating system(s) are you seeing the problem on?

What browser(s) are you seeing the problem on?

Safari

What version of Bootstrap are you using?

5.3.1

Start with the reduced HTML example and inspect Bootstrap's floating-label styling for date and time inputs in Safari on macOS. Compare empty and populated controls, and consider the issue resolved when an empty date or time field is visually distinguishable from one with a selected value.
