I have a strange problem:
I'm using Webpack (with Vue-CLI) + HMR. When I try to change styles in the browser in DevTools, then my page itself changes the styles - it removes some of them (screenshots below).
I understand that the problem is in the Hot Reload Webpack, because some Vue-Components styles remain, and some are deleted. So I can not change the styles in the sidebar and I have to reload the page every time to get the styles back in place.
Below is added my package.json and webpack.base.conf.js.
Thank you in advance!
P.S. Also I use SASS with SASS-Loader.
