Missing events in the har file after the page is loaded

[talwararjun4]

I noticed that the HAR file is generated immediately on page load event completion. Imagine the following usecase -
I navigated to gmail. the moment the page load event completed the har file got generated.

Now i opened my mail, then the sent folder and then opened the trash folder.

All these events do not result in a page load event firing and hence dont not get captured anywhere in the har file (which is already written). (All of these are ajax calls i guess)

How do I get those events in the har file ?
