Apple - If I use Safari in full-screen mode, I can’t open a new window via keyboard shortcut unless I simply toggle the “File” menu. Bug or feature?

This is a known issue at Apple and after nearly 2 years — and two major macOS updates — it still has not been addressed.

For anyone still frustrated by this seemingly basic issue, it still exists in Safari 14.0.1 running on macOS Bug Sur 11.0.1 (20B29). That means this issue has survived two full major macOS releases and two major Safari updates.

Additionally, I reported this issue on Apple’s official feedback (bug tracking) system on Mar 20, 2019 and it was closed it on Mar 25, 2019 as follows:

I find it fairly stunning that two years later this issue still exists.
