"Previous result" link for search results does not work

[anarchivist]

UV version:

 universalviewer@3.0.0 in sul-purl-uat

I'm submitting a:

• bug report

Current behavior:

When navigating through search results, the "previous result" link does not respond; the "next result" works as expected as however.

Expected behavior:

Based on the changes related to #46, I'm expecting that the previous result link should take me to the previous page that contains matches for the search.

Steps to reproduce:

• Load UV for a purl in sul-purl-uat (e.g. https://sul-purl-uat.stanford.edu/zb477wc3656)
• Type in a search term (e.g. indictment) and submit
• Click the "Next Result" one or more times
• Clicking previous result does not respond

We've tracked this down to adding the zoomToSearchResultEnabled: false config option. It appears that UV attached the events to the previous button when zooming into the result. We're investigating possible solutions, but will most likely end up submitting a ticket to UV about this.
