I am using Brave on macOS High Sierra. There is a dock setting that allows windows to be minimized when double clicking their title bars. The Brave browser seems to ignore this setting, and double clicking the title bar maximizes the browser.
The ideal behavior would be for the Brave browser to respect system settings the user chooses.
Brave Version: 0.20.19 (beta) (though the problem happens on other versions as well)
OS: macOS High Sierra
