3. Right click to open context menu,
   • Exptected Result: 'Cell' menu item should be disabled.
   • Actual Result: It's possible to select 'Cell' to open sub menu.

• There is no need to create the "tagName" variable. It's used only once, so you can use element.getName() directly. You may do contextMenuTags[ element.getName() ].

• The same thing for showContextMenu, we don't need a variable here. The condition can go straight into the if.

• The contextMenuTags definition can be moved out, into the main anonymous function scope, so it's created only once.

• There is an unwanted change in the changelog file at line 1.
