1. Use Ibexa Experience 4.6.6.
2. Edit the article content type and add a taxonomy entry assignment field.
3. Create a new article.

Expected result:
Spacing of empty taxonomy entry assignment field "looks correct".
Actual result:
Spacing of empty taxonomy entry assignment field "looks uneven/broken" because there is an uneven padding of the button to the top and bottom, see screenshot.

The gap is caused by class="ibexa-tag-view-select__selected-list" on the <div>
