416 Requested Range Not Satisfiable when range is wider than content

Question

I get an Error 416 Range Not Satisfiable response when I make an http request with a byte-range of 0-65536. The byte length of the file requested is only 3356.

Reading the spec on byte-range, it sounds like requesting a range that extends beyond the length of the file is okay, and in this case I would expect the entire file to be fetched. https://httpwg.org/specs/rfc9110.html#byte.ranges

A client can limit the number of bytes requested without knowing the size of the selected representation. If the last-pos value is absent, or if the value is greater than or equal to the current length of the representation data, the byte range is interpreted as the remainder of the representation (i.e., the server replaces the value of last-pos with a value that is one less than the current length of the selected representation).

Am I misreading the spec or is this request truly unsatisfiable? I prefer if my client does not need to know the size of the file before making the request; they could vary widely in size. The request is successful if I limit the byte-range to <= the length of the file.

The file requested is a cloud-optimized-geotiff. It is being served by a vite dev server. And the request is made using OpenLayers and geotiff.js.

Here are the DevTools details of the request and response:
