For me the kaspersky injects script on browser anyways, so i dont see certificates visible at all but im slowly being okay with thatEdge Dev is also my main browser.
I'm using the same extensions as you and only 1 from the Google Chrome store: Bitdefender TrafficLight.
The only thing I don't like about Edge Dev is that EV certificates, like the one from my bank are not visible.
See screenshot Edge Dev (not visible), Google Chrome (in black) and the "old" Edge (in green):

I have reported it to Microsoft and hopefully they wil do something about it.
I prefer the green option form the "old" Edge.
