If the url is same on each tabsheet, then first webpage load/render correctly, second no (loading partially without images or styles). Third sometimes correctly, next no. Something is missing in my code?
Within the sample application, multiple instances of the same browser will use the same cache. Please make sure to add a cache folder with a unique name for each instance.
I tried set unique cache folder name earlier, and now i test it again and i don't see any change.
My demo project with cachefoldername works on your computer correctly?
