What happened?

I have a sample C++ program where in I have a main span that lasts for 10 seconds.
Span 1 - 0-10 seconds
Now I have 5 children of Span 1
Span 2-6 - 2-8 seconds (duration of 6 seconds)

So, actual self time should be 4 seconds, however I get a self time of -14 seconds.

Steps to reproduce

Create 1 span with 4-5 child spans with each having a duration just smaller than the parent span.

Expected behavior

Self time should be positive, however it is not.
