If you click the 3d view in the below fiddle, so that the document is in focus, you can then press the arrow keys on the keyboard to change the OrbitControls pan. This is what I was expecting since
enableKeys = true by default in the OrbitControls source code.
If you comment out the r122 imports in the fiddle, and uncomment the r123 imports, the arrow key bindings have stopped working despite
enableKeys = true is still default in the OrbitControls r123 and r124 source code.

I’ve only checked in the Edge browser.
