htmlunit: IllegalStateException: No script object associated with the Page

I guess it happens when

A page with frames is being parsed, and
One of frames changes URL
Then HtmlUnit tries to generate an “unload” event for the page which is not fully parsed yet (and therefore has getScriptableObject() == null).

I have a reproducible case in Selenide framework: https://github.com/selenide/selenide/blob/master/src/test/java/integration/FrameWaitTest.java

Try to run it several times: it fails time-to-time with the following error:

org.openqa.selenium.WebDriverException: java.lang.IllegalStateException: No script object associated with the Page. class: 'com.gargoylesoftware.htmlunit.html.HtmlPage' url: 'http://127.0.0.1:14702/page_with_frames.html' content: <!DOCTYPE html>
