I didn't remove the master cylinder cover when I compressed the caliper on first side (driver side). Could that have messed something up?

The master cylinder cover is vented to allow for pressure to escape and return as the brake fluid heats up/expands and cools down/contracts. I highly doubt you messed something up.
Just to clarify, the pedal only starts to drop when you start the vehicle correct? Also, what brand and material are your replacement brake pads? Did you have the rotors resurfaced? I'm guessing you didn't, so are there uneven spots/gouges in the rotor? Did you burnish the pads to the rotor?

ABS sensors (wheel speed sensors) are completely separate from your hydraulic brake system. (The sensors are magnets that create a voltage by being close to a reluctor wheel typically mounted in the hub or on the axle shaft. That voltage is interpreted by a module and computed into a speed.) This just isn't possible on our vehicle or any vehicle that I've ever worked on.
You do not have to open the bleeders to compress the caliper piston.
