3. Hit enter on "link" button for the link dialog to open
4. Press "escape" key to close the dialog
5. Notice that the focus goes to the editor instead of the link button

Focus should go back to the link button.

It's a similar case to the #4783 one. We decided then to add appropriate info into our accessibility help dialog. Probably the information about the focus change after closing dialogs should also be added to the dialog.

Agreed, this one can be fixed with similar information in the a11y help plugin under the editor dialog section.
