[Feature]: Separate `launchPersistentContext` argument to set initial URL about playwright HOT 4 CLOSED

For anyone else looking into something similar, I grepped through parts of the Chromium source and it appears that the kiosk restrictions remain present even with both of the flags --kiosk and --no-startup-window - the only problem is that Chromium has no idea how to make a non-existent window full-screen.

To solve that I ended up opening a CDP session and getting the windowId with Browser.getWindowForTarget before requesting fullscreen with Browser.setWindowBounds (parameters {windowId, bounds: {windowState: "fullscreen"}}.

Despite solving my issue through a sort of workaround I still wonder why Playwright by default disallows arguments that do not start with a hyphen, i.e. opening a specific URL in the default context on startup.

It may also be desirable to allow setting an initial URL for non-persistent contexts too, i.e. making it possible to have the default context automatically navigate to a user-supplied URL when using launch.

This would require removing the --no-startup-window flag when isPersistent is false and appending the URL in question too.

This parameters you pass in launch/launchPersistentContext are fully customizable with a combination of ignoreDefaultArgs and args. We settled over time on the default arguments that we have today, they give you the most flexible control over the browser from the very beginning of the process run, there are no plans to change it.

That is nearly true - it isn't possible to 'specify page to be opened', which seems like a fairly arbitrary limitation.
