All,
I have set up a test app. so you can see this behaviour. There is a multi-value checkbox on screen. If you run it with Chrome, IE or Firefox, the buttons act as expected: the disable button disables both values, the enable button enables them both, whether checked or not, and whether or not one is focussed when a button is clicked.
If you try the steps below in Edge though, it breaks down.
Microsoft Edge 42.17134.1.0
Microsoft EdgeHTML 17.17134
1. Run the page. Check a box, and leave focus in the checkbox.
2. Click the disable button - only the checkbox that had focus greys out, although they are both disabled.
3. Click the enable button - only one checkbox is enabled. The one that had focus previously does not enable again.
The same behaviour occurs if a box is checked then unchecked. It happens only when focus is in a checkbox then a button is pressed directly.
Another test is to run the screen and hit the disable button - the checkboxes do not grey out even though they are disabled.
