VS Code extension folding with multiple lines of decorators is broken

Currently folding in VS Code hides too much of the folded item, so you can't identify it.
For example folding
```
@open
@complex model customSecurityAttributeValue {
}
```

shows the following:

Whereas folding:
```
@open
@complex model customSecurityAttributeValue {
dooo: int32;
hooo: int32;
vooo: int32;
gooo: int32;
mooo: int32;
zooo: int32;
booo: int32;
}
```
shows:

Expected:
In both cases, the content of the `model` should be folded

Actual:
Both cases are broken, albeit differently.
