Describe the Bug
In v3, you would run ionic serve and whenever changes were made to the scss files in the project, the styling would be applied to the app without reloading the page or restarting the app.

This was amazing from a design perspective because changes could be made to the scss files and the results could be seen immediately in the app.

In v4 this is not longer the case. Changing any scss file causes a rebuild event of the entire app, which causes the app to reload. This means you lose any state you had.

The development/design experience has worsened dramatically in this regard from v3 to v4. I do appreciate that this is due to the change in the build process (using the ng CLI) but this does not excuse the worsened development experience. I don't even think stencil does then when adjusting styles.

There must be a webpack or some form of config that can be set while in ionic serve mode? If not this should be raised with the Angular CLI team.

As it stands now, the development time for ionic v4 apps when styling pages has seriously deteriorated and something needs to be done.
