My problem is not the backspace problem - I reported it as a separate issue where xml tags in tickets responses are dropped from the saved response. This worked in 1.9.x.@[deleted] suggestion to attach the xml instead of inline, while it works, is not useful for the type of repsonses we often make where xml code is interspersed through the response.As I said, that is a separate ticket that I suspect will not get resolved as the free version of redactor is no longer supported and has not been for a while.
