Clicking search result in modal window from manuscript detail page does not go to search result

To reproduce:

- Navigate to the manuscript detail page of a particular manuscript
- Open the global search modal (not the manuscript-specific search pane) by clicking "Search" in the navigation bar
- Search for something and click on a chant that is not in the manuscript whose detail page you are currently looking at

Expected behavior: Clicking the search result takes you to the manuscript detail view of that chant. In other words, something similar to what currently happens if you do a search in the search modal from the home page.
Current behavior: The url changes but the modal stays open and the current page does not change.

Compare the global search modal behavior from the home page with the same modal opened on a manuscript detail page. Trace what happens when a result for a chant in another manuscript is clicked; done means the URL changes, the corresponding manuscript detail view appears, and the modal closes.
