three.js: Errors in the threejs.org editor

Description of the problem

In the r113 editor (https://threejs.org/editor/), the following issues occured:

Menubar.Edit.js:161 Uncaught TypeError: Cannot read property 'isShaderMaterial' of undefined
    at Menubar.Edit.js:161
    at Scene.traverse (three.module.js:5707)
    at UIRow.<anonymous> (Menubar.Edit.js:157)

Sidebar.Object.js:571 Uncaught TypeError: Cannot set property 'needsUpdate' of undefined
    at UIBoolean.update (Sidebar.Object.js:571)

Sidebar.Object.js:571 Uncaught TypeError: Cannot set property 'needsUpdate' of undefined
    at UIBoolean.update (Sidebar.Object.js:571)

This was from attempting to click objects and set the shadows flags to true in the ‘Camera’ example scene. A log warning found 15 times when looking in the log:

three.module.js:18347 THREE.WebGLProgram: gl.getProgramInfoLog() C:\fakepath(231,25-83): warning X3571: pow(f, e) will not work for negative f, use abs(f) or conditionally handle negative values if you expect them

Two ‘not cached’ errors from google analytics showed up at the top of the log:
