We noticed a couple of issues that can be reproduced using the Layout->Windows->Modality example in Feature Explorer using standalone SmartClient_v83p_2014-10-18_PowerEdition, just change the line for field1 to the following:
{name: "field1", editorType: "comboBox", valueMap: ["foo", "bar"], defaultValue: "foo"},
1. The preselected value "foo" can not be Tab highlighted in the created window, this happens in IE(10), Firefox and Chrome.
2. After make a selection, either "foo" or "bar", Tab through the window, the selection can be highlighted in Firefox and Chrome, but not in IE.
