Steps

1. Connect to ESP32 based device using USB mode (it will have to use repl file transfer)
2. open a file from the device
3. File shown in the editor has extra empty lines inserted every other line.

Description

When reading via USB the files come accross with extra empty lines inserted i.e.

import board
import neopixel

from adafruit_led_animation.animation.comet import Comet
from adafruit_led_animation.animation.rainbow import Rainbow
from adafruit_led_animation.color import GREEN

becomes:

import board

import neopixel



from adafruit_led_animation.animation.comet import Comet

from adafruit_led_animation.animation.rainbow import Rainbow

from adafruit_led_animation.color import GREEN

Additional information

Using the web mode instead of USB on the same device and browser works correctly and the file is shown normally without the extra lines inserted.
