Group the Comment, Defects, Evidence and Test Run Custom fields into a Findings section within the execution page

A new section named "Findings" must be provided on the execution page to group the defects, evidence, comments and custom fields sections.

This section is collapsed when there are no artifacts (defects, evidence, or comments) focusing the user on what's most important (the test details section) in order to execute the test.

The sub-sections will also be displayed in a list layout.
