Description
Binary: ocean engine sweeps recursively
When we have a branch and one of the branch is a function start, we would not show the outgoing edges:
This can be quite misleading, especially at a quick glance.
Repro steps:
- Open the attached binary
- Go to 0x14000119b
- Press P to make a new function
This phenomena is more often times seen in obfuscated code

Research direction
Reproduce the issue with the attached binary: open it, go to 0x14000119b, and press P to create a function. Trace how the branch graph handles a target that is also a function start; done means the branch's outgoing edges are displayed in this case, including for the reported obfuscated-code pattern.
