Be careful how you use that word, "shorted"... :-)
Bypass caps can be a few millimeters away and still be ok, though it is
certainly best practice to place them as close to the device's pins as
possible. On a breadboard, definitely no long jumpers between them and
the device, but being at opposite ends of a 5-hole bus won't be an
issue; there's not enough stray capacitance or inductance in those bus
bars to make any difference, and the wavelengths don't start to get that
short until you hit gigahertz. Even a couple pre-formed jumpers (the
kind that sit flat against the board) in between won't cause any real
issues.
