Summary
Deno run with --allow-read and --deny-read flags results in allowed
Details

Summary

deno run --allow-read --deny-read main.ts results in allowed, even though 'deny' should be stronger. Same with all global unary permissions given as --allow-* --deny-*.

Details

Caused by the fast exit logic in #22894.

PoC

Run the above command expecting no permissions to be passed.

Impact

This only affects a nonsensical combination of flags, so there shouldn't be a real impact on the userbase.
