addNodeParams reloads whole iframe, should only change url

[JJPandari]

Description

I have an extension on hyperspace portal, which is a react app, plugged into the portal as an iframe, communicating with the portal using Luigi: https://portal.hyperspace.tools.sap/projects/sf-demo-ext/components/sf-demo-ext-ui/sf-ring-deployment

I use addNodeParams to add some params to the url of the hosting website, and this function not only update the url, but also reloads the whole iframe.

Expected result

visit the extension, you can see "Service Version" combobox. Select a version in it, the version should be updated to current url, which is working, but also the whole extension/iframe is reloaded when you select, which is unwanted. As a react app, my extension will rerender data in the page, but labels like "Service Version", "Quality Status" will remain unchanged.

Actual result

When selected a new version, the whole page blinks/reloads, while as a react app it should only rerender charts, tables, not the whole page.

Steps to reproduce

(See the expected result and actual result sections)

Troubleshooting

This unwanted reload behavior happens after I add a addNodeParams call to update the url. Looking at that function's implementation, I can see it essentially does a window.history.pushState, and a LuigiConfig.configChanged(). pushState should only change the url, but never reload the page, I suspect configChanged reloads the whole iframe.
