Problem with module MPU6050

Here is the result of my tests with 2 IDEs: WEB IDE 0.72.1 and Espruino Native IDE 0.72.1
I use the same hardware based on PICO, with the following code:

I2C3.setup({scl:A8, sda:B4, bitrate:100000});
const MPU = require("MPU6050").connect(I2C3);
// 2nd parameter is the fifoRate. The DMP output frequency = 200Hz / (1 + fifoRate)
const DMP = require("MPU6050_DMP").create(MPU, 3);

function pidLoop(args) {
  var data = DMP.getData();
  if(data !== undefined) console.log(DMP.getYawPitchRoll(data));
}

setWatch(pidLoop, B5, { repeat:true, edge:'rising' });

We see:

• 1 - WEB IDE without Minification
  An error LOW_MEMORY

• 2 - Espruino Native IDE without Minification
  No error, Upload ok, working ok

• 3 - WEB IDE with Minification (Esprima Offline)
  "TypeError" errors on MPU6050 module but not on MPU6050_DM module whose size is 31561 bytes
  A syntax error ...

• 4 - Espruino Native IDE with Minification (Esprima Offline)
  No error, Upload ok, the size of the module MPU6050_DM = 17182 bytes
  Operation ok

It's strange the modules do not have the same size.
Apparently the 2 IDEs do not use the same modules.
