[🐛 Bug]: OS incorrectly shows as Windows in session page

[isc-aray]

What happened?

We just upgraded from Helm chart 0.37.4 to 0.38.4, and with the new version, Selenium now seems to think that our autoscaling chrome node containers are running Windows, when they are in fact running Linux. For us, this just amounts to a visual bug where the sessions UI incorrectly shows the Windows logo instead of Tux, since nobody at our organization has capabilities requesting a specific platform, but I guess it could cause bigger problems for anyone who's actually creating capabilities that need specific operating systems.

Note for security reasons I cannot provide the full YAML configuration, but I have included the relevant bits related to the autoscaler and chromeNode.

Command used to start Selenium Grid with Docker (or Kubernetes)

...
autoscaling:
  enabled: true
  scalingType: job
  scalingStrategy:
    strategy: default

chromeNode:
  enabled: true
  terminationGracePeriodSeconds: 3600
  scaledOptions:
    maxReplicaCount: 50
    minReplicaCount: 0
  extraEnvironmentVariables:
    - name: SE_VNC_NO_PASSWORD
      value: "true"
    - name: SE_VNC_VIEW_ONLY
      value: "true"
...

Don't worry, it will be fixed in Grid core 4.28.0 via SeleniumHQ/selenium#15036
To get the right Linux icon on Grid UI, you can explicit provide the platformName in each node config. For example

    firefoxNode:
      resources:
        limits:
          memory: "2Gi"
          cpu: "1"
      hpa:
        platformName: "Linux"

With that, ensure from code automation that you also set capability platformName for request. For example in Python

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.setPlatformName("Linux")
