sap.m.Select not recognized as readonly when editable is set to false

[wurst0815]

OpenUI5 version:
latest and older
Browser/version (+device/version):
any
Any other tested browsers/devices(OK/FAIL):

URL (minimal example if possible):
https://sapui5.hana.ondemand.com/#/entity/sap.m.Select/sample/sap.m.sample.Select

User/password (if required and possible - do not post any confidential information here):

Steps to reproduce the problem:

1. set the property "editable" to false
2. use keyboard navigation to set focus on the select control

Same is with sap.m.MultiComboBox (and maybe other controls, maybe Screen-Reader compatibility with "editable"-property set to false should be checked in general...)

What is the expected result?
Screen-Reader should recognize the control as "read-only"

What happens instead?
Screen-Reader does not recognize the control as "read-only" and announces that value of the control can be changed. When the control gets focus, it appears to be editable, which is not true.
Any other information? (attach screenshot if possible)
