Hello,
I found an issue in IE 11 when calling an alert message with onblur. I have recreated the issue inside a very basic mini application. Please find the application code here:
<!DOCTYPE html>
<html>
<body>
<form action="demo_form.asp">
First name: <input type="text" name="FirstName" onblur="myFunction()" value="Mickey"><br>
Last name: <input type="text" name="LastName" value="Mouse"><br>
</form>
<script>
function myFunction() {
window.alert("I am an alert box!");
}
</script>
</body>
</html>
Steps to reproduce:
1. Open the mini application in IE 11:
Version: 11.447.14393.0
Update Versions: 11.0.37 (KB3197655)
2. Open an additional window (does not need to be IE, it can be any application)
3. Click back on the mini application without minimizing the additional window
4. Click anywhere within the First name field
5. Use the mouse to click out of the First name field
6. You will see the alert message appear on top of the additional window instead of the mini application. This is the issue.
The issue does not recreate itself when using Tab to move outside of the field, only with the mouse click.
Please research and respond with any information or root cause.
Thanks!
