Pressing 'Enter' when an issue is selected in the 'Issue Table' shouldn't change focus

The focus changes to the 'Editor' component when selecting an issue and pressing 'Enter' inside the 'Issue Table' . This prevents the user from quickly going over the issue properties of multiple issues as it forces him to change the focus to the issue table each time he presses enter. This behavior diverges from that of the other existing Axivion plugins.
