Bug 182754 – console.group and console.groupCollapsed should log all arguments

• Status: NEW
• Component: Web Inspector

Reproduction steps:

1. Visit https://chemical-willow.glitch.me in Safari Technology Preview (Release 49 (Safari 11.2, WebKit 13606.1.3.3))
2. Open the console and look at the logs

Expected behavior:

The logs should contain all args passed into the console functions, resulting in the following logs for each console function(group and groupCollapsed).

```
1
{key: "1"}
1 2
1 {key: "2"}
demo
demo 2
demo {key: "2"}
```

Actual Behavior:

Safari seems to only log the first input.


```
1
Object
1
1

```
