Description
Discussed in https://github.com/posit-dev/positron/discussions/3555
Originally posted by jeffkeller-einc June 13, 2024
When I use browser() inside of a function, and run that function, I get a little brown irregular pentagon indicator of the execution position. If I step through the function with n in the console, this indicator gets duplicated and starts to wander into the code.

Research direction
Start by reproducing the issue from the linked discussion using browser() inside a function, then step with n in the R console. Trace the debugger position indicator as it duplicates and wanders into the code; done means a single indicator remains at the actual execution position while stepping.
