[🐛 Bug]: OpenQA.Selenium.WebDriverException : no such execution context

[MJB222398]

What happened?

This is an intermittent issue (happening maybe once in 200 tests or so in my production solution).

Opened a RemoteWebDriver instance and attempted to navigate to a URL and got this exception:

OpenQA.Selenium.WebDriverException : no such execution context
  (Session info: MicrosoftEdge=123.0.2420.65)
at OpenQA.Selenium.WebDriver.UnpackAndThrowOnError(Response errorResponse, String commandToExecute)
   at OpenQA.Selenium.WebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)
   at OpenQA.Selenium.WebDriver.set_Url(String value)

How can we reproduce the issue?

Can try to make this but won't be straight forward. Wondering if logs give enough to go on?

This is a typical chromedriver message, e.g. https://bugs.chromium.org/p/chromedriver/issues/detail?id=4474&can=2&q=no%20such%20execution%20context or https://bugs.chromium.org/p/chromedriver/issues/detail?id=4687&can=2&q=no%20such%20execution%20context

So i would expect this to happen without the grid and there is not mutch to do than report an chromedriver issue. I use a try / catch block in my java code to detect this and rerun another browser instance.

@joerg1985 I don't believe I have ever seen this issue on Chrome, only on Edge.

I created this PR #13978 to support the same issue that I have encountered, as I am also having some trouble on my end when there's not enough details to debug what's the primary issue that causing this no such execution context
