fix: strict type check for cross realms (#21669)
Deno v1.39 introduces `vm.runInNewContext`. This may cause problems when using `Object.prototype.isPrototypeOf` to check built-in types. ```js import vm from "node:vm"; const err = new Error(); const crossErr = vm.runInNewContext(`new Error()`); console.assert( !(crossErr instanceof Error) ); console.assert( Object.getPrototypeOf(err) !== Object.getPrototypeOf(crossErr) ); ``` This PR changes to check using internal slots solves them. --- current: ``` > import vm from "node:vm"; undefined > vm.runInNewContext(`new Error("message")`) Error {} > vm.runInNewContext(`new Date("2018-12-10T02:26:59.002Z")`) Date {} ``` this PR: ``` > import vm from "node:vm"; undefined > vm.runInNewContext(`new Error("message")`) Error: message at <anonymous>:1:1 > vm.runInNewContext(`new Date("2018-12-10T02:26:59.002Z")`) 2018-12-10T02:26:59.002Z ``` --------- Co-authored-by: Bartek IwaƄczuk <biwanczuk@gmail.com>
