Issue Summary

The link Fullscreen" link icon does not have an href value defined, and additionally it is not accessible with a keyboard.

Steps to Reproduce

1. Launch the URL
2. In the Insights menu, select any object schema.
3. Click on the "oracledb-11g-prod" button, just beside the "Referenced Server:" text, in the "Can we get this server request approved?" page.
4. Then the "Object Overview" modal will display.
5. Click on the "Show graph" icon button.
6. Click on the "Tree" button. Then the graph will display in the tree view, just beside the "Referenced objects" heading.

Actual Results

When keyboard-only or screen reader users navigate through the "Object overview modal", the Fullscreen" link icon does not receive keyboard support and thus they will not be able to access the full-screen functionality of the modal box, but with the help of the mouse the functionality of the full-screen mode can be accessed. This happened due to a lack of href value.

Expected Results

• Provide href with a certain value in the <a> tag, so that the "Fullscreen" icon will receive the keyboard support.
• As far as semantics and styling is concerned, the <a> element isn't a link (:link) unless it has an [href] attribute. A side-effect of this is that an <a> element without [href] won't be in the tabbing order by default.

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available.
