Issue Summary

The instruction text associated with "Issue" and "Epic link" combobox is not associated with the form field.

Steps to Reproduce

1. Activate the "Create" button from the header section.
2. Observe that "Create Issue" modal dialog has appeared on the screen.
3. Using screen reader navigate to the "Issue" input field.
4. Ensure that instruction text is not associated with the form field.

Actual Results

The instruction "Begin typing to search for issues to link. If you leave it blank, no link will be made." and "Choose an epic to assign this issue to." are not associated with their respective form fields "Issue" and "Epic link". As a result, screen reader users might miss out important instructions.

Expected Results

Apply the following changes:
• Add "aria-describedby" attribute to the form field.
• Reference the "id" value of the element used to display the instruction text in the "aria-describedby" attribute.
