POST Fetch with timeout in URL Loops Requests 10 times
Scenario: I am running a node.js UI that proxies requests to the backend API. When `timeout=10` (or any valid timeout) is located in the request URL, the request will be proxied at the timeout interval ten times. In this example, every ten seconds it will reattempt for ten attempts.
If I run the same code in another browser's console, it is only executed once.
I am suspecting that there is some pre-parsing of the URL that is occurring that is making this happen.
Fetch Command: ``` await fetch("http://localhost:8080/config?timeout=10", {
"credentials": "omit",
"headers": {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:132.0) Gecko/20100101 Firefox/132.0",
"Accept": "application/json",
"Accept-Language": "en-US,en;q=0.5",
"Content-Type": "application/json",
"Sec-Fetch-Dest": "empty",
"Sec-Fetch-Mode": "cors",
"Sec-Fetch-Site": "same-origin",
"Priority": "u=0",
"Timeout": 40
}, "referrer": "http://localhost:8080/swagger/index.html?config=/config/swagger", "method": "POST", "mode": "cors"
}); ```
In the POST API, there is a 30 second sleep, then it raises a 408 error code.
Environment: Firefox 132.0.2 (64-bit) Windows 10

Determined it didn't matter what parameters are passed. If a Fetch command occurs for a POST that returns 408, it will reattempt the request up to 10 times. I found a super old bug report that has the same scenario.
