Bug Summary and Steps to Reproduce
While stepping through assembly when starting from a breakpoint, the lines will shift up by one (while one appears to be duplicated).
Note that the second time the lines ares stepped over they seem to be correct and don't shift.
I'm not sure if it's related to the coroutine code used in the target application, however the addresses don't seem to change so I don't believe the instruction pointer is misaligned.

Research direction
Start with the reported cppvsdbg launch configuration and reproduce stepping through assembly from a breakpoint on Windows 10 with C/C++ extension v1.17.5. Compare the displayed disassembly lines and instruction addresses on the first and second steps; done means the lines remain aligned without a duplicated or one-line offset.
