[🐛 Bug]: execution got stuck for hours Thread [Forwarding getWindowHandles on session d2bae387ae17d6ad28e3c0f2ca3f9035 to remote] (Stepping)

[avishekhece]

What happened?

In a new window, there's an alert and if I do anything on the parent window then the new window will close immediately, so to counter this, I tried to switch to its default content frame then tried to switch to the new window and I am getting two windows but not able to switch it. It is getting stuck for hours in the below line bold line.

@SuppressWarnings({"unchecked"})
public Set getWindowHandles() {
Response response = execute(DriverCommand.GET_WINDOW_HANDLES);
Object value = response.getValue();
try {
List returnedValues = (List) value;
return new LinkedHashSet<>(returnedValues);
} catch (ClassCastException ex) {
throw new WebDriverException(
"Returned value cannot be converted to List: " + value, ex);
}
}

How can we reproduce the issue?

In a new popup window where only an alert is present and this window is continuously loading with the alert and if we perform any action like click or manual interference on the execution window then the new window will close.
