Based on #5800 (comment) there should be an option added in preference to enable/disable pinned tabs in new window.

Yes, please. This is the only thing about the Brave browser I don't like.
For my use case, I basically keep email and rss feeds in pinned tabs and I don't want or need them to follow me and take up more resources when I open a new window. The new window is almost always for some separate task. For example, I might want to open a video in a new tab and put it on my second screen while I continue to use the main browser for other things.
