5. Inspect the checkbox element for "Show done epic".

Actual Results

In the Create issue modal for the "Show done epic" checkbox, which is available on activating the Epic link input field has missing roles and states. This will make it the assistive technology users difficult to understand its functionality and state.

Additionally, the checkbox has missing keyboard support.

Expected Results

The name, role, value, states, and properties of user interface components must be programmatically determinable by assistive technologies. Fix this issue by using of the following techniques:
1. Use the HTML <input type="checkbox"> element with a programmatic label.
2. Use the ARIA method:
a. Use the role="checkbox" attribute on the checkbox container.
b. Use the aria-checked="true"/"false" attribute to convey the checked/unchecked state.
c. Provide a programmatic label by using the aria-labelledby attribute or aria-label attribute or wrapping the visible label inside the checkbox element.
