Draggable handle obscured

Problem/Motivation

When multiple values are used in a field, the drag handles are obscured.

Steps to reproduce

• Install Drupal, minimal profile
• Enable field_ui and file modules
• Create a content type with a file field allowing multiple files
• Create a new node of that content type
• Upload several files in that field
• Save this new node
• Create a new Radix subtheme
• Configure this new subtheme to be used for editing content
• Visit the edit screen for the new node

Expected result:

A cross icon representing a drag handle appears inline to the left of each file (see screenshot using Stark)

Actual result:

The cross icon is pushed up and to the left outside it's container, such that only a few pixels of the bottom-right of the drag handle appears (see screenshot using fresh Radix 6 subtheme)

Elsewhere, only the handle's right half is obscured:
• Add and enable the paragraphs module
• Add a paragraph type with a text field
• Add an Entity reference revisions field of reference type: Paragraph to the content type
• Visit the edit screen for the node and add a new paragraph
• Observe only left half of a drag handle is shown, the right half obscured. (See same screenshot using Radix 6)

(Interestingly, I found a reference to this same problem from a decade ago on Drupal 7. So take that for whatever it's worth.)
