Since the library is added unconditionally the corresponding css file is loaded even when there is no need for it.
Furthermore I stepped into another side effect. When using an entity reference paragraph field in a field group and the field group is empty, the field group gets rendered even when the option "Display element also when empty" is disabled. That happens because of the attached library.
1. Download and enable paragraphs and field_group module.
2. Create a paragraph entity.
3. Create a node entity and add an entity reference field to the paragraph entity created in step 2.
4. Add the field created in step 3 into a details fieldgroup with "Display element also when empty" setting disabled.
5. Create content for the new entity without content for the paragraph.
- You will see the field group label rendered without content.
In ParagraphsSummaryFormatter.php add a check if $elements has value before attaching the library.
