Visibility of labels used in attributes of parent rule are checked against rule extension package #28618

Description

@brentleyjones

Description of the bug:

Seems like the visibility of labels used in the default values of a rule is checked against a rule extensions's package instead of the parent rule. This leads to new visibility errors that can't be resolved, especially since we can't override private attributes in a rule extension.

Which category does this issue belong to?

Rules API

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

Parent rule (in rules_apple):

apple_precompiled_resource_bundle = rule(
    ...
    attrs = {
        ...
        "_fallback_infoplist": attr.label(
                allow_single_file = True,
                default = "//apple/internal/resource_rules:Info.plist",
        ),
        ...
    },
    ...
)

Rule extension:

load(
    "@rules_apple//apple:resources.bzl",
    _apple_precompiled_resource_bundle = "apple_precompiled_resource_bundle",
)

RedditResourceBundleInfo = provider(
    "Resource bundle info",
    fields = {
        "bundle_name": "The name of the bundle.",
    },
)

def _apple_precompiled_resource_bundle_impl(ctx):
    providers = ctx.super(_apple_precompiled_resource_bundle).providers
    return providers + [
        RedditResourceBundleInfo(bundle_name = ctx.attr.bundle_name),
    ]

apple_precompiled_resource_bundle = rule(
    implementation = _apple_precompiled_resource_bundle_impl,
    parent = _apple_precompiled_resource_bundle,
)

Error:

ERROR: BUILD.bazel:14:27: in apple_precompiled_resource_bundle rule //Some:Target: Visibility error: target '@@rules_apple+//apple/internal/resource_rules:Info.plist' is not visible from target '//another:extension.bzl'
Recommendation: modify the visibility declaration if you think the dependency is legitimate. For more info see https://bazel.build/concepts/visibility. To set the visibility of that source file target, use the exports_files() function
