gulp-uglify changes behavior of javascript

[Stadly]

See this CodePen. It shows how Parsley.js v2.8.1 changes behavior when uglified by gulp-uglify v3.0.1.

In particular, <input type="date" min="2000-01-02" max="2179-06-06" value="2018-11-23"> is invalidated by the uglified version of Parsley.js, but not when Parsley.js is not uglified.

I just work on the plugin for Gulp. If you have an issue with how UglifyJS minifies, you need to report it to them.
