Block Inserter: "Browse all" button non-functional and close button throws error #728

Describe the bug

Two related issues on the Pattern Creator page: (1) The "Browse all" button under "Add new block" is non-functional and does nothing when clicked, and (2) When the block inserter is manually opened via the + button and then closed using the X button, a React error is thrown in the console: Uncaught TypeError: t is not a function at onClick (index.js:73:23).
