When trying to test & debug Mock Debug in any mode except "external", stackFrameRequests (running in mockDebug.ts) make no attempt to return the Source location for any given stackframe, which means no source highlighting & "unkown source"s galore in testing.
Is this intentional? Why not provide an example for retrieving source locations from a debugger + DA running inline? Especially since only the inline mode is ready to fork & debug out-of-the-box, & is the only option for web-extensions, any examples of source location retrieval would be incredibly helpful.
