[Feature]: Provide ability to pass CancellationToken into Async methods

[FutureTD]

Is there a way to use cancellation tokens to cancel async operations?

It would be helpful to have most of the async methods able to be cancelled. Especially methods like

await page.GotoAsync("https://github.com/");

which would then be:

await page.GotoAsync("https://github.com/", cancellationToken);

Yea, it would be nice.
In our project on some cases we are using "dirty task cancellation" similar to this https://devblogs.microsoft.com/pfxteam/how-do-i-cancel-non-cancelable-async-operations/

I think that for most cases it would be more than enough to pass the CancellationToken to CreateAsync() and then check the cancellation in all operations.

Closing it, since there are no plans to support it. Browser interactions like clicks, fills are all not cancelable, so even if we would provide it, it would be a kinda fake cancel, and a certain action would still run in the background.

@mxschmitt this is true from a browser user perspective, but I think it's really not about cancelling any actions/commands but more about cancelling potential waiting process for the callbacks of the commands.

As far as I can see all commands are sent via SendMessageToServerAsync() - and for each command the callback is being awaited. Why should it not be reasonable to cancel this instead of waiting for callback to be fulfilled? For example when I want to cancel the execution (e.g: some test run, or some executable), why would I still need to wait until the await page.GotoAsync("https://github.com/") command is having some callback. I just want the execution to be stopped gracefully as fast as possible and no "hanging" execution.

I would really appreciate, if you would reconsider your decision or give us some alternative way to gracefully cancel pending commands.
