Bare "type" used as expression statement without semicolon causes syntax error

[jakebailey]

Describe the bug

This is code that appears on DefinitelyTyped; type in this context is just an expression statement, not a keyword. Adding a semicolon fixes the problem, though in this case, we are hitting this bug because DT is now formatting with dprint, which can't parse the tree to add the semicolon.

Input code

avplay.setListener({
  onsubtitlechange: (duration, subtitles, type, attributes) => {
      duration // $ExpectType string
      subtitles // $ExpectType string
      type // $ExpectType string
      attributes // $ExpectType AVPlaySubtitleAttribute[]
  }
})

Likely, this is some missing ASI rule.
