Does a dispenser tether cloaked spies?

I know that, as a cloaked spy, I can recharge my watch from a dispenser. In fact, a L3 dispenser can recharge my watch faster than it drains. However, I know that dispensers display a glowing tether to units that they are resupplying. If I cloak next to (or on top of) an enemy dispenser, will I get tethered and thus be revealed to detail-oriented Engies and Pyros?

Solution 1:

No, cloaked spies will not be tethered by dispensers.

It's the same mechanic as to whether medics can attach medigun beams to cloaked spies. They can't, and I know flickering from being bumped doesn't change it.

Most special effects are hidden while cloaked, with notable exceptions being milk/jarate/blood/water drips and fire.
