Version History causes Item page to hang

[tdonohue]

Describe the bug
Found during Testathon. If an Item has a version history table, then visiting the Item page will cause the page to "hang" / become unresponsive. The page also will take a very long time to load via SSR...it only loads via CSR.

An example item on the Sandbox is this one: http://localhost:4000/entities/publication/a7c2fbbc-9138-400f-b593-81ee1489023e
("Clinical and Virological Features of Dengue in Vietnamese Infants")

To Reproduce
Steps to reproduce the behavior:

1. On the Sandbox site search for Clinical Virological Infants: https://sandbox.dspace.org/search?query=Clinical%20Virological%20Infants&spc.page=1
2. The first result will be the item linked above ("Clinical and Virological Features of Dengue in Vietnamese Infants")
3. Click on that result to visit the Item page
4. The page will load immediately but then sometimes will "hang". For example: buttons and links on the page will no longer react to hoverover of the mouse and similar.
5. Reloading the page (to trigger SSR) will cause the page to not be responsive. Eventually it will load via SSR but data may be missing and i18n translations may be missing. Again, after loading, the page will "hang"

Expected behavior
Obviously, Version History should now cause the page to hang
