Describe the issue

In the current snapshot version (to be released), the right border of a validated input is not visible:

<div class="input-group has-validation">
  <span class="input-group-text">@</span>
  <div class="form-floating is-invalid">
    <input type="text" class="form-control is-invalid" id="floatingInputGroup2" placeholder="Username" required="">
    <label for="floatingInputGroup2">Username</label>
  </div>
  <button type="button" class="btn btn-outline-secondary">Button</button>
  <div class="invalid-feedback">
    Please choose a username.
  </div>
</div>

(same thing with classic .form-control elements, it's not just with .form-floating inputs)

Last year the same issue #33204 had been fixed with PR #33211.

I don't know what happen since, but the right border is broken again.
