The behavior isn't specified, however MDN
(https://developer.mozilla.org/en-US/docs/Glossary/Prefetch#resource_prefetching)
states the priority of such elements should be lower than for elements
with the fetchpriority attribute.

https://web.dev/fetch-priority/#browser-priority-and-fetchpriority
states fetchpriority has no effect on this element.

For web-compatibility, that behavior is desired for Gecko too.
