After Clicking "Custom Dataset Terms" cannot view Files Tab

What steps does it take to reproduce the issue?
Datasets with "Custom Dataset Terms" show a link for the custom terms (above the tabs). If you click on that link - the "terms" tab becomes active and I see the custom terms, BUT now if I click the "Files" tab, the files briefly "show" and then the page goes back to the custom terms display.

See this dataset on demo.dataverse: https://demo.dataverse.org/dataset.xhtml?persistentId=doi:10.70122/FK2/EEX7VM

Reproduce the issue on the demo.dataverse dataset linked in the report: click the Custom Dataset Terms link, then select the Files tab. Trace the tab navigation behavior from there; done means the Files tab remains active and displays the file list, while Versions and Metadata continue to work.
