fix: embed.js doesn't expands iframes height (#18301)
also including some refactoring: - add `// @ts-check` - use Map to completely avoid prototype pollution - assign random id to each iframe for reduce chance to brute-force attack, and leak of iframe counts - check iframe.contentWindow and MessageEvent.source to validate message is coming from correct iframe (it works on latest Chrome/Firefox/Safari but I'm not sure this is allowed by spec) follow-up of #17420 fix #18299
