Stuck on loading animation when saving file over USB

[Neradoc]

On MacOS, with a RP2040 Zero board.

• connected to the board with the USB workflow
• allowed access to the drive (not called CIRCUITPY)
• write in a new file print("Hello")
• save as "text.py" in the board's drive via the Save as button
• page stuck on the rotating "loading blinka" animation

The following message output repeats in the console:

Thanks, this should be a quick bug fix. It looks like it's missing the let keyword on https://github.com/circuitpython/web-editor/blob/main/assets/js/common/usb-file-transfer.js#L156.

Oops, no. It's defined in the function header. I'll take a look though. I like these little puzzles. :)
