Exactly.

But AIUI, it is the server that lists the options it will support, and the  
browser that chooses which one will be used. Or is it the other way around?

If it is the browser that chooses, and if, as reported, it chooses the  
"first", is that the first in its list, or the first in the server's list?  
If it is in _its_ list, then could reordering the list solve the problem?

But, in any case, it will be easier for concerned users to fix their  
browsers, or persuade the implementors to do so, than to persuade all the  
servers out there to change.
