Issues with App Icon in Issue Navigator, both old and new UI in Cloud

Recently we’ve noticed that our app icon integrated to Issue Navigator in both new and old Cloud UI looks weird:

I have contacted vendor support, it resulted in creation of issue in Atlassian Connect JIRA: [ACJIRA-1391] App Icon incorrectly aligned in Issue Navigator in old Jira UI - Ecosystem Jira
