`Show source code in disassembly view` not work

Bug type: Debugger & Disassembly

Describe the bug

• OS and Version: Linux (Ubuntu 20LTS)
• VS Code Version: 1.63.0
• C/C++ Extension Version: v1.7.1
• Other extensions you installed (and if the issue persists after disabling them):
• A clear and concise description of what the bug is.

To Reproduce
Please include a code sample and launch.json configuration.
launch.json: the generated default.
code sample: just c++ hello world.

Steps to reproduce the behavior:

1. Check the Settings - Features - Debug - [Disassembly View: Show source code], make sure it's TRUE;
2. In the editor, write any good c++ code, then press F5 to start a normal debug, and pause at some breakpoint.
3. Right click inside the code area, select Open Disassembly View to launch the disassembly view.
4. As it shows, there's only assembly code. The c++ source code is NOT inlined within the assembly code.

Additional context
If applicable, please include logging by adding "logging": { "engineLogging": true, "trace": true, "traceResponse": true } in your launch.json
Add any other context about the problem here including log or error messages in your Debug Console or Output windows.

What I want is: c++ source code can be inlined within the disassembly code together, just like the visual studio behaves:

Reproduce the issue on Ubuntu with VS Code 1.63.0, the C/C++ extension v1.7.1, the generated launch.json, and the Disassembly View: Show source code setting enabled. Pause a C++ hello-world program at a breakpoint and open the disassembly view; done means C++ source is shown inline with the assembly as described.
