Subject: Transpile also dependencies in node_modules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some of the dependencies in node_modules, such as "p-queue", are not ES5
compatible, so they need to be transpiled to work in older browsers like
Internet Explorer 11.

Besides not excluding the dependencies for babel-loader in
"webpack.common.js" the global Babel configuration must be defined in
"babel.config.js", as in Babel 7.X, when ".babelrc.js" is used, all the
dependencies in "node_modules" are ignored (even if whitelisted in the
configuration file itself).
