[wasm] Add another error snippet (#656)

On Windows helix I am getting this error:

    [13:34:28] crit: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
                      ---> OpenQA.Selenium.WebDriverException: unknown error: Chrome failed to start: crashed.

Add another snippet so that Activation is repeated when we get this
error.
