Different grouping in select 1.4.10 vs. 1.5.0 vs. 1.5.4 (CodePens attached)

Hi guys,

after updating angular from 1.4.9 to 1.5.6 I experience a different grouping behaviour in the select when using ng-options.

Please take a look on my codepens:

http://codepen.io/hoody/pen/gMMPBg (Angular 1.4.10: expected behaviour)
http://codepen.io/hoody/pen/EyyPeJ (Angular 1.5.0: new optgroup container around option)
http://codepen.io/hoody/pen/ZOOQjq (Angular 1.5.6: new optgroup container around option AND empty optgroup before listing of optgroups)

Is this a known bug? Will it be fixed? Do you have a workaround for me? :)

Greetings,
Stefan

Thanks for the report, very thorough.
Quick Answer: Not a known bug, yes, no. 💃

Does this actually impact the usability of the app, apart from the visual change?

Sorry, I was a bit too quick. This is not a bug, but a known documented breaking change: https://code.angularjs.org/snapshot/docs/guide/migration#directives-ngoptions-

If an option has the group '' it is put into the group ''. You need to put the option into the group undefined for it to be put into the top level.

Although it does look like a bug that in 1.5.6 an empty group is created.

Nevertheless, thanks for your quick reply. With the help of the link I could fix the issue. 👍
