The problem with the IVY incremental builds is still broken… we are working on a fix - see https://github.com/angular/angular/pull/31655, which fixes it but not the correct way.

@kolkov’s problem was not IVY related and was fixed in @angular-devkit/build-angular@0.802.0-rc.0 as he reports by this commit: https://github.com/angular/angular-cli/commit/6649483d86a27abb1eb2392a612f4d1bdf7a8cfc
