Dear Maintainer,
The ESP-IDF code for the server is:
-- >8 --
static bool gpio_state = CONFIG_ESP32PSKO_INITIAL;
#define ROOT_GET_START \
"<meta charset=utf-8>" \
"<meta name=viewport content='width=device-width, initial-scale=1'>" \
"<title>esp32psko</title>" \
"<form method=post>" \
"<table>" \
"<tr><td>Current:</td><td>"
#define ROOT_GET_PART2 \
"</td></tr>" \
"<tr><td><label for=value>New:</label></td><td><input type=checkbox
id=value name=value"
#define ROOT_GET_PART3 \
"> <input type=submit value=Set></td></tr>" \
"</table>" \
"</form>"
static esp_err_t http_root_get_handler(httpd_req_t *req)
{
httpd_resp_send_chunk(req, ROOT_GET_START, sizeof(ROOT_GET_START) - 1);
httpd_resp_send_chunk(req, gpio_state ? "UP" : "DOWN",
HTTPD_RESP_USE_STRLEN);
httpd_resp_send_chunk(req, ROOT_GET_PART2, sizeof(ROOT_GET_PART2) - 1);
if(gpio_state)
httpd_resp_send_chunk(req, " checked", sizeof(" checked") - 1);
httpd_resp_send_chunk(req, ROOT_GET_PART3, sizeof(ROOT_GET_PART3) - 1);
return httpd_resp_send_chunk(req, NULL, 0);
}

driven by the ESP HTTP server.
When I call this by running "lynx 192.168.1.136",
lynx shows "HTTP/1.1 200 OK" in the status line,
and the rest of the screen is black;
here's a video:

Naturally, this isn't an ergonomic way to test this, so here are two
recorded transactions, which behave identically:

I get the same thing when I run
