What Operating System are you using (both controller, and any agents involved in the problem)?

Jenkins on Kubernetes

Reproduction steps

• Setup a system message with warning level
• Navigate from main page to a job page
• Notice that the header is different

I'm ussing following JCasC for the systemMessage

appearance:
  customHeader:
    systemMessage:
      level: warning
      message: "*****"

Expected Results

Header is similar on all page

Actual Results

Anything else?

No response

Are you interested in contributing a fix?

I've been following https://weekly.ci.jenkins.io/design-library/Banner/
Locally I can't reproduce this.
Could be related to the bootstrap5 plugin. I think that also defines the css class alert-warning
Can you check when you have an admin monitor in the upper right how it looks there?

[jonesbusy]

Hi,

You are right, the node monitor is also changed on the job page
