The browser options allow to color the event background in accordance with the event's severity.
In the current use case, priority has precedence over severity. A prioritization by severity level is not useful.
The operators cannot recognize the actual priority of the event after transfer to incident management. It happens that unimportant events for a test environment with high severity are being worked on faster than events for a production system with lower severity but higher priority.
The request is to color the event background in accordance with the event's priority.
