I created a test app to get the latest package.json along with trying to update other files like the webpack.config.js, i did it successfully but now i have an issue, my updated app has sidemenus, they work fine, for the first click, after that the backdrop doesn't go away and i cant click anything inside the app, if i remove the backdrop html element from chrome dev tools, it works as expected.
This issue doesn't happen in the test sidemenu app, nor in my app before update.
