Comments are attached to wrong nodes as inner position

Steps to reproduce:

1. Use Esprima demo page: https://esprima.org/demo/parse.html
2. Copy paste this code inside the editor

function a() {
   var b = 5;
   /* Comment1 */
}
/* Comment2 */
{
   /* Comment 3 */
}

3. Check option (checkbox) "Attach comments"

Expected output:
All comments are trailing or leading with exception of the inner comment for "Comment 3"

Actual output:

Reproduce the issue in the Esprima demo parse page using the supplied JavaScript and the “Attach comments” option. Trace comment attachment from that entry point and verify that comments are not duplicated or attached to the wrong nodes, with Comment 3 retained as the inner comment for its block.
