Code

(Usual webpack setup; no specific code needed to repro)

Expected Behavior

Autogenerated SSL certificate should be accepted by common browsers.

Actual Behavior

As of MacOS 10.15, the SSL certificate validation logic is more strict and requires some additional certificate extensions. Ref: https://support.apple.com/en-us/HT210176

For Bugs; How can we reproduce the behavior?

Start up webpack-dev-server with SSL enabled on a MacOS 10.15 system; attempt to hit the server in Chrome (probably Safari as well).

For Features; What is the motivation and/or use-case for the feature?
