Describe the bug

A recent PR to b-tags-input has caused as styling bug.

Now, the input box is shrunk when empty (34 pixels) and no tags are selected. it grows by 4px (38px) when tags are added.

#5544

Removing this CSS definition seems like it would fix the bug to me:

.b-form-tags-list {
    margin-top: -0.25rem;

    .b-form-tag {
      margin-top: 0.25rem;
    }
  }

Steps to reproduce the bug

This can be seen on the Bootstrap-Vue docs page by simply removing tags from the examples. When the list is empty, it will shrink in height by 4px and then grow back by 4px when the tags are re-added.

Expected behavior

The height of the element should be constant (38px) regardless of whether any tags are inputted or not.
