Improve behaviour of Issue Navigator 'Add Columns' search

Summary

In some cases, a customer might not be able to search and select a specific column to add to the issue navigator screen.

Environment

• JIRA
• More than 25 custom fields, which have a common word
  • One of the custom fields is just the common word
  • The common word appears in the search results list more than 25 items down
  • For example the set of custom fields:

    ["a unit", "aa unit", "b unit", "bb unit", "c unit", ... , "zz unit", "unit"]

Steps to Reproduce

1. Create above set of custom fields
2. Open the issue navigator and click on the 'Columns' drop down.
3. Type unit

Expected Results

As the custom field unit is an exact match to the term being searched, it should be displayed first on the list.

Actual Results

Observe that the search results do not display unit and there is no way to narrow them further to get this result.

Workaround

• Rename custom fields
