Bug report

When a ComboBox is disabled, if the user tries to select the value by double click, additional new line is added to the selection

Reproduction of the problem

1. Open the Api ComboBoxDemo
2. Select an item
3. Click on the 'Disable' button
4. Double click in the ComboBox to select the value
5. Paste it

Current behavior

In the Demos a new line is added before the value of the ComboBox. When the same Demo is opened in a Dojo, a part from the text above the ComboBox is also highlighted. (screencast)

Expected/desired behavior

Only the text in ComboBox should be selected even if the widget is disabled.

Workaround

The element holding the down arrow icon could be hidden when the ComboBox is disabled. - Dojo
