[BUG] OpenAI chatGPT 5.2 provider with bing search enabled errors out with > 128 tool calls

[plapsley]

This is for ChatBox 1.18.4 on a Mac M1 running MacOS 15.6.1.

Chat using provider as OpenAI chat completion API, model is gpt-5.2, thinking = heavy. Web search with bing enabled. I asked it:

"XXX is a company that does YYY. What is their funding history? When did they start and how much have they raised, in what rounds, when, and from whom?"

ChatBox fired off a bunch of web queries until this error came back from OpenAI api:

{
"error": {
"message": "Invalid 'messages[28].tool_calls': array too long. Expected an array with maximum length 128, but got an array with length 146 instead.",
"type": "invalid_request_error",
"param": "messages[28].tool_calls",
"code": "array_above_max_length"
}
}
