r3f fixes (#222)

* Minify r3f extension bundle, because it is expected by the React dead code elimination check, since we bundle React in it

* Add children to props, since it is required by React 18 types

* Fix getting context attributes for gl in ReferenceWindow

* Don't bundle threejs in extension

* Fix editor not responding to scene initialization

* Fix SnapshotEditor css
