[question] what changed after version 6.1.1?

I'm using esp-web-tools to flash esp-link on esp8266 devices. This works absolutely fine with esp-web-tools v6.1.1. Yet when using a higher version like 7.5.0, 8,06 or 9.2.1 it won't work.

The manifest is unchanged:
```json
{
"name": "esp-link",
"version": "3.2.47",
"new_install_prompt_erase": false,
"builds": [
{
"chipFamily": "ESP8266",
"parts": [
{ "path": "boot_v1.7.bin", "offset": 0 },
{ "path": "user1.bin", "offset": 4096 },
{ "path": "esp_init_data_default.bin", "offset": 4177920 },
{ "path": "blank.bin", "offset": 4186112 }
]
}
]
}
```
Using version any version higher than 6.1.1 doesnt work.

It flashes, but after flashing it doesnt work on the esp. Connecting via usb gives corrupted data (no matter which baud)

Version 6 works flawlessly.
