thread 'main' panicked at src/display/hunks.rs:517:17: internal error: entered unreachable code

[riadevatix]

Error while diffing these two files, doesn't matter which order I try to diff them.

function MyComponent() {
  return (
    <div>
      hello {' '}
    </div>
  )
}

function MyComponent() {
  return (
    <div>
      hello
    </div>
  )
}
