@{ block format on type adds New Line on pressing ';'

[TanayParikh]

I was anticipating either:

1. Final space added-> @{ Debugger.Launch(); }
2. Both new lines

@{
    Debugger.Launch();
}

This one is rough. FormattingContext.Indentations assumes that each line starts in one context, and contains at most 1 transition to a different context. The formatter cannot represent lines with more than one context switch, such as single-line elements that transition and then transition back.
