Actual Results

The "Pin" / "Unpin" image buttons in "Manage columns" modal dialog lack textual description. As a result, screen reader users will be unable to identify the purpose of these buttons.

Expected Results

Apply the following changes:

• Provide the descriptive label as "Pin" / "Unpin" for the image buttons using aria-label attribute.
• Remove the "Title" attribute from the source of the image buttons.
