PECL downloads broken by chunked encoding

Dear PHP internals, It appears that a (relatively) recent change broke pecl clients: now that chunked encoding is sometimes applied and such responses are probably cached by CDN, pecl clients (at least one from PHP 7.4) fail to download the packages: they can't handle chunked encoding and the size prefix breaks the XML for it. I stumbled upon this issue yesterday but can't tell for sure when exactly it broke because I don't rebuild my images very often but a month ago is was OK. At the same time I discovered a similar issue reported on GitHub: https://github.com/php/web-pecl/issues/119 Could you take a look? Was there a CDN configuration change that could have caused this? It's quite important now, when we rebuild the environment because of the recent CVEs. Thanks!
