Testrail App - Test result details not displayed in full screen

[Claudio Cortellessa]

Hi, as I've integrated Jira and TestRail using the test management plugin from:
https://marketplace.atlassian.com/apps/1213701/testrail-test-management-integration-for-jira?tab=overview&hosting=cloud

As I click on the details of a test that has been ran, all info related to that case such as:
 - Project
 - Milestone
 - Test Run
 - Steps
 - Expected result
 - Related result

Are displayed only on a tiny portion of the screen instead of being displayed properly.
