Interesting, IIRC Espruino interpreter does "wake up" periodically, some timer runs out, it's documented somewhere. So short spikes in power consumption is expected.
Tested with an MDBT42Q breakout @ v.2v08.189, but my baseline is around 5~7uA (measured by an INA226 and Espruino) .
When did you buy the Espruino and the Raytac module? Long shot, but maybe Raytac changed something in the module, and doesn't go as low power as earlier modules did? Got mine with the Bangle kickstarter. Or maybe you uploaded something earlier to the modules that changed fuse bits?
