fromImport property
Whether the current canonicalize invocation comes from an @import
rule.
When evaluating @import rules, URLs should canonicalize to an
import-only file if one exists for the URL being canonicalized.
Otherwise, canonicalization should be identical for @import and @use
rules.
Subclasses should only access this from within calls to canonicalize. Outside of that context, its value is undefined and subject to change.
