Update fetch-later quota expectations by TimvdLippe · Pull Request #41776 · servo/servo

TimvdLippe · 2026-01-08T15:39:05Z

Follows the spec updates per whatwg/fetch#1903
It now expects the explicit requested and quota
fields.

Unfortunately that is sometimes difficult to
determine, since it depends on a couple of things
such as data type and internal structure. Therefore, where we know exactly the result we hardcode the
value. For those where it is less determinate, we
use a function to compute at least an upper-/lowerbound.
