Actual Results

Decorative images have been given descriptive alternate text "ansible admin" and "George Kalpakas authored on 15 September 2018" present in the "Diff" and "Commits" tabs respectively which was found to be unnecessary as they do not convey any additional or important information to screen reader users.

Expected Results

Ensure that decorative images are hidden from screen readers. Apply the following changes:
• Remove the textual description in the form of hidden text from the source code.
• Hide the image using aria-hidden="true" attribute.

Workaround

Currently, there is no known workaround for this behaviour.
