$(fn) acts differently in browsers if jQuery loaded late

Description

If you load jQuery after DOMContentLoaded and load events fired modern browsers will never fire $(fn) while IE will fire it immediately since it doesn't rely on events.

Looking at the code a simple check should be made after setting readyBound: if (document.readyState === 'complete')

return jQuery.ready();

The function passed to $(document).ready() is never called if:

  1. 1) Using Firefox 3.5 or older.
  2. 2) And loading jquery on demand. I.e., by inserting jquery script into <head> dynamically.

How to reproduce:

  1. 1) Open the attached test.html.
  2. 2) Click on the "Load jQuery" link.
  3. 3) Two alerts should arise.

Only the "before ready" alert arises on Firefox 3.5. The "inside ready" alert is never seen there.

The old Firefox don't have document.readyState.
