Test Results tab does not display carriage returns on MacOS

[nooj]

When running tests on MacOS (14.6 and prior), the "Test Results" tab does not move the cursor to the left at the end of a line (ie carriage return '\r'). It only performs a linefeed ('\n').

For example:

Line 1 text.
            Line 2 text.
                        Line 3 text.
                                    Eventu
ally, there is a line wrap.
                           Other lines con
tinue in the same way.

See screenshot at this link: https://community.platformio.org/t/output-terminal-issues-during-testing/43944

The "Terminal" tab correctly displays identical compiler/linker output as the "Test Results" tab. Presumably, whatever code the "Terminal" tab has to handle "\n" on Mac as "\r\n" does not happen in the "Test Results" code.

Here is a project which exhibits the error: https://github.com/platformio/platformio-examples/tree/develop/unit-testing/calculator

To reproduce:

1. Use MacOS.
2. Clone the repo https://github.com/platformio/platformio-examples.
3. Open a new VS Code window.
4. Open the project at platformio-examples/develop/unit-testing/calculator
5. Trust the authors.
6. Open the Testing sidebar.
7. Run tests.
8. View bad output in "Test Results" pane.
