Appium iOS Safari Open new tab, accept alerts and

So I'm testing a web app for which I have to open a new tab, switch to it, do some input, than switch back to the first tab and this more than once. I try to open the new tab this way:

((JavascriptExecutor) AppiumTestBase.getDriver()).executeScript("window.open('http://google.com', '_blank')");

This causes the following alert to appear:

But I'm not able to accept it through automation with Appium. Things that I have tried:

Using the following capabilities: "safariAllowPopups" and "autoAcceptAlerts"
Changing the according settings for safari in the iOS sim
.switchTo().alert().accept(); I also waited for the Popup.
Switchting to native context before accepting the popup
Clicking the pop up by name .findElement(By.name("Allow")).click();

What I have not tried:

Taping on the screen according to the pop-up coordinates. I didn't try this since I'm not sure on how to get the position of the "Allow" button.

And my other question is how would I switch between two tabs? I haven't tried anything yet, but research would suggest that I try it with window contexts.

Some other information:

Currently testing with a iPhoneSE iOS 9.3 Simulator, the solution should work for several configurations
Appium is on the most recent version
The class "AppiumTestBase"s only purpose is to set capabilities and initialize the AppiumDriver

I tried the solution suggested by Atthaboon Sanurt, but it didn't help. There was no alert, but the new window/tab didn't open either.

Here where the problem is reported: https://github.com/appium/appium/issues/6864

So far it looks like there is no solution and plans to fix it.
