If I create a new file while the sidebar is focused, the new file tab does not have focus. It would make sense to focus the new file, since you're most likely to start typing into it. Saving the new file also does not work without first focusing its tab ("save"/"save as" items are disabled in the file menu), but strangely you can still close the new tab without focusing it (either from the menu or with a shortcut).
