IgcMultiColumnComboBox's dropdown list shows behind IgcDialog

[jsakamotoIGJP]

Description

The dropdown list of the IgcMultiColumnComboBox component inside an IgcDialog component appears behind the IgcDialog's content, making it inaccessible to users.

Steps to reproduce

1. Run the application I attached to this issue post.
2. Click on the "Show Dialog" button.
3. Once the dialog appears, click on the icon at the end of the right of the combo box component.

Result

The dropdown list of the IgcMultiColumnComboBox component will appear behind the IgcDialog's content.

Expected result

The dropdown list of the IgcMultiColumnComboBox component must appear in front of the IgcDialog's content.

[!NOTE] see also the issue #755, "IgcDatePicker's dropdown calendar shows behind IgcDialog". It was resolved by adding the open-as-child and is-fixed properties for the IgcDatePicker.
