No? Tons of formatters respect user-introduced whitespace, which is a good thing to do.
I would argue the example posted above is still "consistent" because the rules Prettier follows for line breaks (and everything else) are consistent throughout the codebase. Things will be on one line until the line is too long or complex, and then it will break to multiple lines. The rules don't change depending on who was writing the code, what the code is, or any other factors. It may not be formatted exactly how you want, but that's kind of the whole point. It's formatted how Prettier wants, and that's the only option.
