Turns out the behavior differs between DMG and CGB – in DMG mode, the objects enabled bit is checked before halting the FIFOs, meaning that disabled sprites do not affect Mode 3’s length on the DMG.

The object enabled bit is checked only when popping from the object FIFO. Objects affect timing even when disabled.
