Edit review on chrome webstore as developer

Question

Suppose I'm the developer of a chrome extension (which indeed I am) that is up on the web store and that I want to answer the review of one the users.

Now, if I add/edit my review my previous post gets overridden (even if I AM the developer), making my efforts in helping users useless.

Is there something I'm missing, or is it how it currently works without any way to prevent this from happening?
