v4.1.1 Breaks webpack uglifier

[daveferrara1]

Description

Briefly describe the issue. The newest release throws a webpack error. The result is a non uglified js file so its much larger in file size.

ERROR in p_videojs.js from UglifyJs Unexpected token: name (monitor) [p_videojs.js:49757,6]

Steps to reproduce

"./node_modules/.bin/webpack -p --config webpack.config.js"

the -p flag is important. Make sure not using any extra uglifer plugin. See package.json below.

v4.1.0 works fine.
