Inspector and parent window freeze when attempting to serialize an HTML element

Took me a while to track this one down and I believe it's related to:

https://github.com/statelyai/xstate/issues/4645 https://github.com/statelyai/xstate/issues/4985

I was able to patch @statelyai/inspect package at version 0.4.0 to fix this issue:

I'm not sure if these max depth values are the best they could be, but this did resolve my issue.
