Wrong cursorOffset with formatted JSX text

[Gregoor]

In a similar vein to #12491 (which I am still intending to fix), I found a misplaced cursorOffset issue with code like this

<>a•
  <div>hi</div>
</>

(where • denotes the given cursor position)

When passed into prettier we get:

<>•
  a<div>hi</div>
</>

Which is unexpected, because the a correctly moves down, but the cursor stays up.

Here is code for testing it:

const prettier = require("prettier");
prettier.formatWithCursor(["<>a", "  <div>hi</div>", "</>"].join("\n"), { cursorOffset: 3, parser: 'babel' });

and the runkit to see it in the browser:
