in input-group with border at rounded-start and rounded-end not right with dir= rtl and correct in ltr

[ab2d3e8]

for example :

<div class="input-group mb-3" dir="rtl">
  <button class="btn btn-outline-secondary" type="button" id="button-addon1">Button</button>
  <input type="text" class="form-control" placeholder="" aria-label="Example text with button addon" aria-describedby="button-addon1">
</div>

The appearance is not suitable.
Thanks

Have you ensured that you have included the RTL (Right-to-Left) version of Bootstrap CSS in your HTML file? If I include your example within one of our official RTL example pages, it appears to work correctly.
