[Bug]: Can't launch two Firefox contexts

[Aimeast]

Version

1.50.0 (Playwright for .NET)

Steps to reproduce

static async Task Main(string[] args)
{
    var contextOptions = new BrowserTypeLaunchPersistentContextOptions { Headless = true };
    var playwright = await Playwright.CreateAsync();
    var content1 = await playwright.Firefox.LaunchPersistentContextAsync(@"C:\Users\xx\Desktop\test\ff", contextOptions);
    var content2 = await playwright.Firefox.LaunchPersistentContextAsync(@"C:\Users\xx\Desktop\test\ff", contextOptions);

    var page1 = await content1.NewPageAsync();
    var page2 = await content2.NewPageAsync();

    await page1.CloseAsync();
    await page2.CloseAsync();

    await content1.CloseAsync();
    await content2.CloseAsync();

    playwright.Dispose();
}

Expected behavior

There are no errors after the execution is completed

Actual behavior

When executing on second playwright.Firefox.LaunchPersistentContextAsync,

• First, Firefox pops up the error window: Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

• Then, playwright throw the exception: TargetClosedException. details:

Microsoft.Playwright.TargetClosedException
  HResult=0x80131500
  Message=Target page, context or browser has been closed
Browser logs:

• But, if change to chrome, everything is OK.

var content1 = await playwright.Chromium.LaunchPersistentContextAsync(@"C:\Users\xx\Desktop\test\chrome", contextOptions);
var content2 = await playwright.Chromium.LaunchPersistentContextAsync(@"C:\Users\xx\Desktop\test\chrome", contextOptions);

Additional context

@Aimeast Browsers do not allow two instances to run with the same userDataDir. Firefox shows an error, while Chrome focuses the first instance when you try to launch a second one. This is not supported.
