Submission feedback link doesn't work on Linux

[pistonet]

Describe the bug

The submission feedback link doesn't work. I get an error: "The BROWSE action is not supported on the current platform".
From what I found: gdelmas/IntelliJDashPlugin#73 this might be a common issue with IntelliJ/Java on Linux.

To Reproduce

Steps to reproduce the behavior:

1. Submit an exercise to get the "Submission feedback available popup
2. Click on "Click here to open the feedback"

Expected behavior

I assume it should open the feedback in the user's default web browser, this has never worked.

Screenshots

Environment (please complete the following information):

• Operating System: Kubuntu 18.04 LTS (KDE 5.44.0)
• IntelliJ IDEA version: IntelliJ IDEA 2020.3.2 (Community Edition)
• Version of A+ Courses plugin: 2.0

Somehow the links in the "A+" > "About the A+ Courses Plugin" -dialog work fine though. Even though both of them seem to use com.intellij.ide.BrowserUtil.

Thank you for reporting the bug. You're right about BrowserUtil, we actually changed the link to use it recently. The fix will be available in the next release
