Description
When hitting a function breakpoint, if the source code window is dismissed the No Source window pops up, indicating that the Frame was not module and source code cannot be opened. (See screenshot below).

Note that you can still open source code by using the callstack view. The expected window is "filename not found".
Configuration used:
`
exec-run
`

Research direction
Reproduce the function-breakpoint case using the provided PipeLaunchOptions configuration, dismissing the source window and comparing the No Source result with the callstack view. Trace the handling of the No Source window and verify that the expected result is "filename not found" rather than the message that the frame was not a module.
