Change from 3.7.4 to 3.7.7 caused "failed to allocate temporatry buffer" for sending a webpage in chunks

[PBJ-results]

When going from version 3.7.4 to 3.7.7 I was not able to serve a large page when sending the page in chunks:

 AsyncResponseStream *response = request->beginResponseStream("text/html");
        masterControllerPage(*response,hotkeyAUpMaster, hotkeyADownMaster, hotkeyBUpMaster, hotkeyBDownMaster);
        request->send(response);

I would get the following error response when using verbose core debug:
12:45:52.300 -> [165343][E][cbuf.cpp:104] resize(): failed to allocate temporary buffer
12:45:52.300 -> [165350][E][WebResponses.cpp:848] write(): Failed to allocate

Notes:

1. I am writing to an ESP32-WROOM-32D chip and a fair amount of the memory is being gobbled up by the fact that it is also using code from https://github.com/bitluni/ESP32Lib that is outputting to a VGA Monitor using the I²S protocol.
2. function example:

void masterControllerPage(Print& out,String hotkeyAUp, String hotkeyADown, String hotkeyBUp, String hotkeyBDown) {
out.print(" a lot of stuff");
out.print("and things");
}

I currently have no need to go to 3.7.7 but I wanted to let the community & it's developers know.
let me know if you want any more information if you want to duplicate & or solve

@PBJ-results : are you able to reproduce with one of the example or provide a MRE to reproduce please ?
If you are within your app, this is not a valid reproductible use case since anything from your app could impact the memory for example.
If you can please isolate in an example the piece of code and provide us a way to reproduce.
Thanks!

You have an example already you can play with: AsyncResponseStream.

Note that you can control the buffer, which, in your code, forget to do.

Thank you for the quick reply!
I see that I did not control the buffer, in my code good point.
I assume the the buffer size intended to be the size of the entire webpage. Is this correct?

When I have time to look into this deeper, I will see if I can reproduce my issue with simpler code.

I currently think my problem has something to do with not setting a buffer size and going from <StreamString.h> to <cbuf.h> in the AsyncResponseStream. (#148)
I wonder if using the out.print(); method above has anything to do with my issue as well.
Thanks again for your response, and I hope you have a wonderful day.
