Babel 7 spread syntax in IE/Edge not working - reactjs

Question

So i have babel 7 installed, along with the plugin "#babel/plugin-proposal-object-rest-spread" included within my preset-env, however I'm still getting the following error as it hasn't transpiled my spread operators back into es2015.
SCRIPT1028: Expected identifier, string or number
I've tried referencing the plugin in the plugin array within my .babelrc file.
My .babelrc file:
{
"presets": [
"#babel/preset-react",
"#babel/preset-env", {
"include": [
"#babel/plugin-proposal-object-rest-spread"
]
}
],
"plugins": [
"#babel/plugin-syntax-dynamic-import",
"#babel/plugin-syntax-import-meta",
"#babel/plugin-proposal-class-properties",
"#babel/plugin-proposal-json-strings",
]
}

Looks like you're using Webpack, and you have babel-loader installed.
That being the case, here are two quick things to check:
Are you sure you're using that loader in your webpack config for js files?
rules: [
{
test: /\.jsx?$/,
loader: 'babel-loader',
exclude: /node_modules/,
},
],
Are there any js assets bypassing Webpack, "missing out" on that loader?
(Edit): And if "no" to those, might you also need "#babel/plugin-transform-spread" to capture spreads in an array, since "#babel/plugin-proposal-object-rest-spread" is object-specific?
