Console insert newline between each argument

I am using [vuejs-logger](https://github.com/justinkames/vuejs-logger) which add a prefix by calling `console.log` with [multiple arguments](https://github.com/justinkames/vuejs-logger/blob/aa6c92aec40fd22a56ac7b0812b8fad967280e87/src/vue-logger.ts#L88). This render the following in VSCode debug console:
```
warn | js:161330:26 |
This should stop
```

In the browser, this is on a single line. In a debug session with Chrome, it is also on a single line, allowing `debug.console.collapseIdenticalLines` to work nicely.

I don't know if it's a bug, or if it's on purpose, but I would much prefer having all arguments of one call in one line.

Reproduce the linked vuejs-logger call that passes a prefix and multiple arguments, then inspect how the VS Code debug console renders that output in the Firefox adapter. Compare it with the single-line browser and Chrome debug-session behavior; done means arguments from one console call render on one line so identical-line collapsing works.
