Regarding the blue "View Ticket on Track" button, I clicked on it expecting it to open in a new window.
Ideally, it would open in a new window or I would not lose context when going back. The icon on the button is commonly used to indicate that something will open in a new window, so if it doesn't do that I think another icon (or none) might eliminate confusion.
Also, we need to keep this in mind when creating links that open in a new window: https://medium.com/@jitbit/target-blank-the-most-underestimated-vulnerability-ever-96e328301f4c
