A resistor running at 85C doesn't strike me as a big problem, it's common for them to be spec'd to higher operating temperature than that. Yes it will eventually cook cheap phenolic PCB, but it's not going to start a fire.
The 24/7 hot running resistor from mains blackened the phenolic PC board, cooked the parts next to it and eventually started smoking. The heat degrades the plastics as well. After a few years, the components are roasted in a bad way.
No fuse, so I hit the horn on that cheap ass chinese junk as any EE would do, sent it off expecting UL would have a finding. The UL product-specific safety standard only cared if the thing worked or not (which it did). Other standards have requirements for a fuse, component temperature testing etc. It did not call any of those standards, which IMHO it should.
Many of the UL standards are quite old going back to the early 1920's like the one for soldering irons. They have accumulated wisdom but fail to update them, and then harmonized standards (IEC) are a second, competing set. It does make a mess. Manufacturers will certify to a lax, old standard whenever possible.
UL can only issue a "warning" about a counterfeit UL mark i.e.
https://www.ul.com/news/public-notices they are only concerned protecting their brand name.
UL 817 Standard for Cord Sets and Power-Supply Cords USD $800 plus subscription costs.
The irony of the chinese aggregating all safety standards and posting them for free, whereas you or I can't look at them in order to highlight any shortcoming, is another crime.
It's a massive problem to allow unsafe, fake certified products into your country. The certification agencies have their own ecosystem profiting from test services, approvals, selling standards. It adds a massive burden to SME and does nothing to stop junk from coming in at our ports.
