What is the problem or limitation you are having?

Currently, the url argument in set_content() is required. But it stands to reason that, if you are directly setting raw HTML content, that content doesn't have a URL associated with it.

What we can currently do is pass an empty string to url:
my_webview.set_content("", content=html_content)

But that's clunky.

Describe the solution you'd like

In the set_content() function, make the url argument optional.

Describe alternatives you've considered

Perhaps #2851 can make this issue obsolete.
