Current behavior: After searching for a word, the "Next Result" button doesn't work after multiple clicks

Expected behavior: User is able to navigate through the search results using the Next/Previous Result buttons

Steps to reproduce:

1. Go to https://universalviewer.io/examples/#?c=&m=&s=&cv=&manifest=http%3A%2F%2Fwellcomelibrary.org%2Fiiif%2Fb18035723%2Fmanifest&xywh=1367%2C2636%2C817%2C614
2. Search for something with multiple results (best with "münchen", as the issue appears after less clicks. "wird" will also work, but after a lot more clicks)
3. Click the Next Result button a few times. The button will become unresponisve and the console will output the following:

Uncaught TypeError: Cannot read property 'externalResource' of undefined

This appears to be fixed in v4: https://uv-v4.netlify.app/#?c=&m=&cv=32&manifest=https%3A%2F%2Fwellcomelibrary.org%2Fiiif%2Fb18035723%2Fmanifest
