#### Preserve blank lines between JSX attributes (#19161 by @Poliklot)

Prettier now keeps one existing blank line between JSX attributes, consistent with how it preserves blank lines in many other places. Multiple blank lines are still collapsed to one.

<!-- prettier-ignore -->
```jsx
// Input
<Button
  type="submit"
  variant="primary"
  size="large"



  disabled={isSubmitting}
  onClick={handleSubmit}
/>;

// Prettier stable
<Button
  type="submit"
  variant="primary"
  size="large"
  disabled={isSubmitting}
  onClick={handleSubmit}
/>;

// Prettier main
<Button
  type="submit"
  variant="primary"
  size="large"

  disabled={isSubmitting}
  onClick={handleSubmit}
/>;
```
