Steps to reproduce the problem:
1. Used Chrome to place an order with Tesco
2. Having ordered goods, I tried to pay using a Master Card
3.The validation process crashed part way through. 

What is the expected behavior?
The Validation Process should have completed and permitted payment details to be acted upon.

What went wrong?
When the Screen starting the Validation  of my card got part way through, the screen went blank and nothing then happened.   Eventually, I used Microsoft Edge to get onto the Tesco site and all went exactly as planned and the Validation process completed satisfactorily.

Did this work before? N/A
