Some time ago "backspace-to-go-back" functionality have been removed from Chrome. However as a proficient user I had to install extension to enable this functionality again. Now while inline editing text in Pro it is possible to remove some text with backspace but eventually one of it's clicks is going to lead to being thrown back.
I know this is kinda specific situation but I bet that there might be some other users affected as you probably have quite some devs here. Personally I use this extension: https://chrome.google.com/webstore/detail/backspace-to-go-back/nlffgllnjjkheddehpolbanogdeaogbc
Maybe you can guys take a look at this and prevent this from happening on your side? In a meantime I will cope with this somehow.
