UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36

Steps to reproduce the problem:
1. User enters "A" in input type="text"
2. User hits ENTER key 
2. onchange handler dynamically sets input's value to "B"
3. User enters "A" back again in the input (NOTE: re-entering any value other than "A", which was previously entered, will not reproduce the problem) 
4. Users hits ENTER
4. onchange event is not fired

What is the expected behavior?
As other browsers behave (including Safari, Firefox, and IE), the onchange event should be fired even if the user re-enters a previous value.

What went wrong?
The onchange event is not fired when the user re-inputs the previously entered value with ENTER key.
Attached is a simple my-input.html which reproduced the problem with 2 types of inputs.
