if conditional statement being negated after bundling process

[coding-sldr123]

I'm submitting a bug report

Webpack Version:
5.70.0

Babel Core Version:
7.17.5

Babel Loader Version:
8.2.3

Please tell us about your environment:
AWS Amplify

I am running into a weird bug using webpack/babel. I am experiencing a difference between how my code looks in the GUI where I wrote it and in the browser. I have an if statement that starts off something like this:

if (condition1 || condition2 || condition3) return;

after webpack bundling it looks like this, via the browser debuggers (firefox and chrome):

if (!(condition1 || condition2 || condition3)) return;

It is completing negating the if statement.

excerpts from webpack file:

{
test: /.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: "babel-loader",
options: {
plugins: [
[
"@babel/plugin-transform-runtime",
{
"corejs": 3,
"helpers": true,
"regenerator": true
}
]
],
presets: [
'@babel/preset-env',
'@babel/preset-react'
]
}
},
}

..

output: {
filename: 'bundle.js',
publicPath: '/'
},
devServer: {
historyApiFallback:true
},
plugins: [
new HtmlWebpackPlugin({
template: './src/index.htm'
}),
new webpack.ProvidePlugin({
process: 'process/browser',
}),

...

This is a bug being produced in a react project, in a component within a button click event.
