Which release are you on? Is this the same as #21?
Community firmware release 3 based on Marlin v2.0.7.1
Nope - not related - the bed heats up, but the problem is related to no de-bouncing of the strain gauge.

Your comments regarding the strain gauge made me think, so I went ahead, enabled DIRECT_PIN_CONTROL to directly talk to the strain gauge.
When COM_PIN is set to 0 it turns off reporting of the Z-endstop. To test this, move the hot-end so it is triggered (blue led), then set COM_PIN to LOW (via M42 P5 S0). The blue LED will turn off.
M119 also says that z_min = open. When you then turn on COM_PIN to 1, the Z-endstop is still not triggered.
If you then apply even more force to the strain gauge, it is then triggering again. So the combination of COM_PIN 0, a delay, and COM_PIN 1 is essentially the act of pressing the "tare" or "zero" key on your kitchen scale. It is self-calibrating (when the Marlin tells it to) which begs the question what that potmeter is even doing there. Maybe all it defines is the threshold. You tare it via firmware, but the threshold (how many "grams" it takes for it to trigger) is set via the potmeter.

I've done some improvements in eede631.
