Confusing process of updating Global Compatibility Level
### Is your proposal related to a problem?

<!--
  Provide a clear and concise description of what the problem is.
  For example, "I'm always frustrated when..."
-->

When selected and submitted, the Global Compatibility Level for Schema Registry doesn't update automatically. You need to update the page to see the changes.

### Describe the solution you'd like

<!--
  Provide a clear and concise description of what you want to happen.
-->

The Global Compatibility Level changes automatically once a new option from the drop down menu is selected and submitted; no updates of the page, going back and forth between tabs is needed.

### Describe alternatives you've considered

<!--
  Let us know about other solutions you've tried or researched.
-->

### Additional context

<!--
  Is there anything else you can add about the proposal?
  You might want to link to related issues here, if you haven't already.
-->

When Global Compatibility Level is selected and submitted, there is a strange visual bug -- as if a pop-up tries to open but fails.
