bug example

When I Insert on fly JS.
Execution sequence are incorrect.
In all browsers first pop's "event 1", last "event 2".
On browser's based on WebKit (Google Crome & Safari) first pop's "event 2", last "event 1".
This can broke logic of JavaScript program.

Please see attached example on different browser's.
