urequests.get ignores content-length header

When connecting a server running this php sample

<?php
set_time_limit(0);
ob_start();
header('Content-type: text/plain');
header("Content-Encoding: none");
echo "OK";
header('Content-Length: '.ob_get_length());
header('Connection: close');
ob_end_flush();
@ob_flush();
flush();
if(session_id()) session_write_close();
sleep(10);
die("Client should never see this");
?>

if you view this page in a web browser or in curl you will only get OK, however urequests.get ignores the content length and waits for sleep to finish and get the die message before returning content, urequests.head has the same issue except you can't get the status_code

i managed to fix this, but my fix does nothing when i import it even though it works if i copy/paste the library inside my script
this was how i fixed it

    @property
    def content(self):
        if self._cached is None:
            try:
                if(self.headers["Content-Length"]):
                    self._cached = self.raw.read(int(self.headers["Content-Length"]))
                else:
                    self._cached = self.raw.read()
            finally:
                self.raw.close()
                self.raw = None
        return self._cached

Start with the urequests content property and the get/head entry points, then reproduce the behavior against the PHP sample in the issue. Verify that the response stops at the declared Content-Length instead of waiting for later output, while preserving the returned content and status information.
