I have found that https://github.com/jenkinsci/blueocean-plugin/blob/68d5f0bd92a9b0f0ba08e52028dea07031468840/blueocean-core-js/src/js/storage.js#L56 is a big problem if you have different jenkins instances under one same domain or installing new plugins clears all localStorage properties in the ns "jenkins-instance"

That is not desired for many properties like e.g. DEBUG statements of the logger. Why would I want to clear that preference when I e.g. install a new plugin?

Expected behaviour for logging and preferences stored in the localStorage are to persist and not be cleared. Only jenkins-instance/installInfo should be cleared.
