It seems following error are randomly occurs on snapshot test. (For example: #9008)

Microsoft.Playwright.PlaywrightException : net::ERR_CONNECTION_REFUSED at http://localhost:8089/index.html

As far as I've comparing succeed log and error log.
Test [FAIL] log occurred nearly same time as webserver startup log.
And it seems Playwright don't wait webserver startup and don't retry automatically.

So I've added simple SpinWait to check active port.
Then it seems successfully working.

Note: It may be better to replace SpinWait based TCP port check to something like Microsoft.Extensions.Primitives.IChangeToken based notifications later. (and add support ICancellationToken)
