Formatting bug or silly settings by me?

I have a CSHTML file.

It contains a call to RenderpartialAsync() inside a code nugget.

Then I manually format the nugget over three lines the formatting is sensible.

However, if I write the nugget on one line:

@{ await Html.RenderPartialAsync("_Candidates", Model.Candidates); }

Then the formatting is mental:

Is this a bug or have I got a daft setting somewhere?
