Allow showing history for other fields other than description

[chasewallis]

First of all, you're my hero.

Second, we've got a number of fields that this diff tool would be nice to use in, not just description. Test steps, User Story, and a bunch of custom ones. Is it possible to enable this for any field, not just description?

Thanks! @chasewallis as long as we can locate those elements in the DOM reliably it should be totally doable. The relevant code is in the findDiffContainers function in content.js.

  findDiffContainers() {
    const updateElements = Array.from(document.querySelectorAll('div'))
      .filter(el => el.textContent.includes('updated the Description'));

    return updateElements.map(el => {
      const possibleDiffContainer = el.nextElementSibling;
      return (possibleDiffContainer && possibleDiffContainer.children.length === 3) ? possibleDiffContainer : null;
    }).filter(Boolean);
  },
