Some data previews on details page can crash the page

[travjenkins]

Bug
Open a details page with huge data previews (link can be found in Slack)
See the page load fine
See the data preview stays in loading
See data preview stays in loading for a long time
The page will probably crash or fully freeze

Expected
We prevent this "run away" loading of preview. If documents are too large to render we should stop loading and inform the user their documents are too big to preview.

Screenshots
Preview grew to this until I stopped the page before it froze the browser

Desktop (please complete the following information):

• OS: [e.g. Windows]
• Browser [e.g. chrome, safari]
