white-space:nowrap; causes paragraphs to blow outside of wrapping divs when paragraph is collapsed

Problem/Motivation

The paragraphs-widget.css file from paragraphs-widget.css (contrib/paragraphs) is being overridden in thunder_admin. Both css files declare the following:

.js .paragraph-top .paragraph-summary{
  grid-column:1 / 5;
  -ms-grid-column:1;
  -ms-grid-column-span:5;
  -ms-grid-row:2;
  -ms-grid-row-span:1;
  grid-row:2 / span 1;
  overflow:hidden;
  white-space:nowrap;
}

The white-space:nowrap; portion causes the following overflow issue.

Steps to reproduce

Add a text-based paragraphs component with at least 250 characters or so (depends on screen-width).

Proposed resolution

Add `white-space:normal` as the thunder_admin override instead of `white-space:nowrap`.
