Wrap EAD abstract in HTML tag

[marlo-longley]

This makes the UI consistent whether we display data from scopeandcontents or abstract Thanks to @thatbudakguy for finding this issue + pairing !

What in the UI is inconsistent whether it's from the abstract or ?scopeandcontents or abstract?

[marlo-longley]

If it's a <scopeandcontents> EAD field, <p> tag is getting stored in Solr and returned. <abstract> is just raw unwrapped text stored in Solr. So when we conditionally display one or the other in the same place in the markup, there is a difference in text padding within the same list.

This text came from <scopeandcontents>

This text came from <abstract>

this has implications for the responsive truncator as well — you can't calculate the height of a bare text node using getBoundingClientRect(), so the logic there only works when the field contents are wrapped in some sort of element.

(if there's a "wrap this in an element if it isn't already wrapped" type helper, we could just as easily use that in the component template, I just didn't see anything like that, so this was our solution for now).

an example of the truncator issue can be seen in the brief display for the Hemingway collection fixture (you can find it by searching "hemingway"). it has both an <abstract> and a <scopecontent>, and we choose to display the abstract in the brief result. because it's not wrapped in a tag, the truncator can't calculate the height of the content, so the "view more" button doesn't display because truncation is not detected.

<div class="col al-document-abstract-or-scope" data-arclight-truncate="true">
      <div class="content"> This artificial collection includes articles by or about Hemingway, movie posters and photographs, manuscript letters, printed and miscellaneous materials about Ernest Hemingway and his books, diaries of Ernest's uncle, George R. Hemingway, and the organizational records of the Michigan Hemingway Society. </div>
      ...
</div>

cf. some of the items on the repositories page, which use their <scopecontent> rather than abstract, and so the content is wrapped in a <p> tag. the height can be calculated, and the "view more" toggle displays:

<div class="col al-document-abstract-or-scope truncated" data-arclight-truncate="true">
      <div class="content"><p>Images of students and student activities including track meets, women basketball players, dormitory rooms, picnics and off-campus excursions, commencement activities (including decoration of the arcades as parlors), and theatricals; there are also photographs of campus buildings before and after the 1906 earthquake and of Leland Stanford Jr.'s railroad track on campus. Non-Stanford images include Yosemite and scenes from a European trip. </p>
      ...
</div>
