Pressing ⌘+N while on a Pinned Tab reloads the Tab.

I stumbled upon this while writing on my Notion (which is a Pinned Tab).

1. I pinned a page on Notion (like my most frequent Notion page) - Let's say "Dashboard"
2. I navigate around to a different page - Let's say "Notes"
3. I write stuff on "Notes".
4. I press ⌘+N
5. It creates a new Window (as expected)
6. But it also unexpectedly reloads the Pinned Tab, back to "Dashboard"

I think this is a bug?

Expected Behavior: I'm still on "Notes" with what I'm writing. Since ⌘+N assumes that I just created a new Window.
