Amen! Creating solutions to problem we invent. There needs to be a line between UI state and application state. I've had similar issues with MVVM in WPF. Do you really need a observable property for "UserClickedThisSoMakeButtonGreenAndShiftThisPanelOverALittleBit" in your view model? I'm exaggerating of course, but there is a line. There is nothing wrong with UI specific code in your component.cs code-behind, same story for react.
