If last tab in a window is notes tab, close tab will not close the window [RC]

Steps to reproduce:

My settings:

Whenever I create a window, it opens notes, and when I try to use CMD+W to close the tab (and the window), the tab seems to refresh and the window does not close.

(I haven't yet tested this with a different "New tabs open with" setting.)

Expected behavior:

I'd expect closing the last tab in a window to also close the whole window.

Vlad Safari doesn't have the concept of a "notes" tab, so I can't reproduce it in Safari. If I have a window with three tabs and hit CMD+W three times, the entire window closes as expected.
