The 'View source' button has disappeared out of sight

Overview: Instance page. Detail view. Here we have implemented a button labelled 'View source'. When clicking you get to the record in source format. This is implemented for apx. 11 test record. The search below is on one of these test records. The detailed view screen has got so wide, so the button disappear out of sight.

Steps to repro:

1. Login to FOLIO snapshot stable, go to Inventory
2. In the search box, do a search on Contributor: "werner'

Expected result:
The button would display in upper right corner - see UIIN-93.

Actual result:
The button display but you have to horisontal scroll to get to it (in normal display) - see attached screen dump.
