I’ve also had this same issue where styles are inconsistent between debug and production mode. This isn’t always the case, sometimes the styles are correct in production mode, sometimes they aren’t. It only seems to affect colours and fonts, I haven’t noticed inconsistencies in other styling areas.
Why do paper-sider styles affect LoginView?
It feels like the styles are going into one big CSS and are accessible to all, whether they are needed regardless or not.
Is it possible to separate them?
