* Test: should record images inside iframe with blob url after iframe was reloaded

* Handle negative ids in rrdom correctly

When iframes get inserted they create untracked elements, both on the dom and rrdom side.
Because they are untracked they generate negative numbers when fetching the id from mirror.
This creates a problem when comparing and fetching ids across mirrors.
This commit tries to get away from using negative ids as much as possible in rrdom's comparisons

* Update packages/rrdom/src/diff.ts

Co-authored-by: Yun Feng <yun.feng@anu.edu.au>

* Start unserialized nodes at -2

This way we don't accidentally think of them as mirror misses

* Set unserialized id starting number at -2

* Remove duplication
