After update to 4.4.0 I can see a circumflex at start of dump, as following image:  I could not found any commit related to this change. **Pre-edit:** seems related to #31446 and f0a59d3eabcd29709f6c2a11fe73e0a78728f67e, but I still can't understand what mean `^` here (I am using the web version of dump).
