Bug input group

[hotgeart]

Hi,

We can't use input group if input-group-text is more than 2-3 characters : https://getbootstrap.com/docs/4.1/components/input-group/

code:

<input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
<div class="input-group-append">
    <span class="input-group-text" id="basic-addon2">@example.com</span>
</div>

Result:
