ngChange not always fired on select

[stejanse]

Using ngChange on a selectbox is not working properly when selecting options bij pressing keys. The second ngChange event that should be fired never happens. For reproducing I created a Plunker:

Steps to reproduce:

1. Focus on the selectbox, but don't have it opened.
2. The counter next to the selectbox counts the number of ngChange events.
3. Press 'O' once, counter increases to 1.
4. Press 'O' twice, counter does not increase.
5. Now press 'O' a number of times, the ngChange event works perfectly.

As far as I know the bug occurs in all browsers and at least in version 1.2.26, 1.3.2, 1.3.4 and 1.3.6.

This is a duplicate of #9134 (and a few other issues) and only happens when there is no default empty option specified.

It is a Chrome bug (and has been reported here).

OK, let's close this as a duplicate of #9134.
