Create issue modal dialog : The list items/options which are present for "Project" and "Issue Type" combo-box are not announcing by screen reader

Issue Description

On "Create issue" modal dialog there is Editable combo-box for "Project" and "Issue Type" field for which there are list items/options which are not announcing by screen reader when user navigates through it. In addition when user selects a list item/option from this combo-box the focus is moving to "Configure Fields" button inappropriately.

STR

1. Turn on screen reader and navigate to "Create" link present in header region and activate it.
2. Navigate to "Issue Type" link and press down arrow key which will list options for "Issue Type" field.
3. Select any one option/list item and press Enter key. Observe focus moves to "Configure fields" button inappropriately

Actual Behaviour

The options for "Project" and "Issue Type" field is not announcing when user navigates through it using up/down key. When user selects any option/list item item from "Project" and "Issue Type" field the focus does not stay on that particular field. As a result navigating with such editable combo-box will be confusing experience for screen reader users.

Expected behaviour

The options/list items which appears for "Project" and "Issue Type" field should be announce by screen reader. When user selects any option/list item item from "Project" and "Issue Type" field the focus should ideally stay on that particular field.
