[Bug]: page.waitForLoadState api not behaving as per expectation

Version

1.44.1

Steps to reproduce

Page does not wait for load state, but when I do page.content I get page is still navigating error.

can't post the actual page due some issues. But this is happening frequently.

1) Why waitFor load state does not wait ? What is the exact behaviour of this api. From doc its not clear.

I open an html form in browser which trigger a url which in turn trigger many more urls.

2) How do I know in this case that my page is loaded completely?

code I am using

page.waitForResponse("url", options, ()->page.setContent(html))
page.waitForLoadState(LoadState.LOAD, new Page.WaitForLoadStateOptions().setTimeout(30000));
page.content()

com.microsoft.playwright.PlaywrightException: Error {
  message='Unable to retrieve content because the page is navigating and changing the content.
  name='Error
  stack='Error: Unable to retrieve content because the page is navigating and changing the content.
