Web Firmware Installer missing file for Waveshare ESP32-S3-Tiny

[PChild]

Trying to use the web firmware installer for Waveshare ESP32-S3-Tiny and the install fails due to a missing file:

Excerpt from browser console:

This is easy to see/reproduce without the web installer functionality by clicking the "DOWNLOAD BOOTLOADER combined.bin" button at the bottom of the page. It leads to the same looking AWS not found error
