PCB Grounding Techniques for High-Power and HDI
Select capacitors with low ESR and high voltage ratings. Normally chassis plane is directly shorted to the ground plane if the return current of the circuit is less. ...

electromagnetism
You are essentially correct. The "floating" wire you have drawn will act as a stray capacitance to ground. Because the shape is a poor shape for a capacitor the capacitance will be very small. So the circuit will look like two capacitors in series, connected to ground, one capacitor being much larger than the other.
Floating Versus Grounded Voltage
Figure 1: Voltage measurement between line (high) and neutral (low) with the neutral tied to a ground reference point. The voltage at the low reference point is often referred to as a "ground" or "earth ground" because it is tied directly to the earth.
Why is there a capacitor between chassis ground and signal
"Ground" is something you grow potatoes in, not a magical sink into which current disappears. "Signal ground" is both the return path for signal currents and a voltage reference called 0V, the latter substantially because of the former (Ott, §3.2). Cable shields are not grounds, they are noise current sources. Shields separate noise currents ...

Capacitor between grounds: Reason and how to decide the value
Its a NLswitchable part that is used for identification only (almost definitely). It appears that they use a capacitor to indicate what kind of board it is visually. On other boards, if the grounds were different on either side I''d say it was a ground connection but the ground is the same so it serves no purpose electrically.

Grounding in mixed-signal systems demystified, Part 1
A term often used in system design is star ground. This term builds on the theory that all voltages in a circuit are referred to as a single ground point, or star ground point. The key feature is that all voltages are measured with respect to a particular point in the ground network, not just to an undefined ground wherever one can clip a probe.

Grounding
Applying single-point or hybrid grounding. Single-point or hybrid ground systems (see Figs. 14.4 and 14.6) help avoid ground current loops caused by voltage potential differences in the ground system. However, they do not help to avoid ground loop currents induced by magnetic fields.
