Javascript's `window.resizeTo` isn't working

Solution 1:

According to this bug report, this is a new feature, not a bug. Specifically:

Two rules:

  1. Can't resize a window/tab that hasn't been created by window.open.
  2. Can't resize a tab if the tab is in a window with more than one tab.

If I understand this "fix" correctly, you can resize only your own popup windows, not the main window.
