Potential Overwriting of setupMiddlewares in devServer

[nanianlisao]

Hello,

I am using the error-overlay-webpack-plugin in my project and I noticed that the devServer.setupMiddlewares is directly reassigned in the plugin's code. This could potentially overwrite any existing middlewares that have been set up.

Here is the code snippet:

error-overlay-webpack-plugin/src/index.js

Lines 36 to 48 in 64bf2c1

	compiler.hooks.afterResolvers.tap(className, ({ options }) => {
	if (devServerEnabled) {
	const originalOnBeforeSetupMiddleware =
	options.devServer.onBeforeSetupMiddleware
	options.devServer.setupMiddlewares = (middlewares, devServer) => {
	if (originalOnBeforeSetupMiddleware) {
	originalOnBeforeSetupMiddleware(devServer)
	}
	middlewares.unshift(errorOverlayMiddleware());
	return middlewares;
	}
	}
	})

Could you please confirm if this is the intended behavior? If so, it might be helpful to add a note in the documentation to inform users about this.

Thank you for your time and assistance.
