Describe the issue

When two dropdowns are used in the same row, they do not work and both are not displayed, only the first one is displayed, the same happens even in the Bootstrap 5 documentation.

In the section Buttons with dropdowns

<div class="input-group">
  <button class="btn btn-outline-secondary dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false">Dropdown</button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action before</a></li>
    <li><a class="dropdown-item" href="#">Another action before</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
  <input type="text" class="form-control" aria-label="Text input with 2 dropdown buttons">
  <button class="btn btn-outline-secondary dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false">Dropdown</button>
  <ul class="dropdown-menu dropdown-menu-end">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>
