Sounds like a reasonably theory but I haven't investigated anything to say for
sure if that is truly what's going on. What curl version are you using when
you experience this?

The server used in your example code speaks HTTP/1.1, is that also the case
for your "real" case?

I'm not aware of any existing issue like this.

Can you be so kind and file this issue in the curl issue tracker on github [1]
so that we don't let this one slip?
