* We weren't recursing into media queries (or @supports etc.) to rewrite hover pseudoclasses
* The early return meant that the stylesWithHoverClass cache wasn't being populated if there were no hover selectors on the stylesheet
- not committing the test, but modifying the existing 'add a hover class to a previously processed css string' as follows shows the problem:

rrweb-snapshot
Snapshot the DOM into a stateful and serializable data structure. Also, provide the ability to rebuild the DOM via snapshot.
API
This module export following methods:
snapshot
snapshot will traverse the DOM and return a stateful and serializable data structure which can represent the current DOM view.
There are several things will be done during snapshot:
- Inline some DOM states into HTML attributes, e.g, HTMLInputElement's value.
- Turn script tags into
noscripttags to avoid scripts being executed. - Try to inline stylesheets to make sure local stylesheets can be used.
- Make relative paths in href, src, CSS to be absolute paths.
- Give an id to each Node, and return the id node map when snapshot finished.
rebuild
rebuild will build the DOM according to the taken snapshot.
There are several things will be done during rebuild:
- Add data-rrid attribute if the Node is an Element.
- Create some extra DOM node like text node to place inline CSS and some states.
- Add data-extra-child-index attribute if Node has some extra child DOM.
serializeNodeWithId
serializeNodeWithId can serialize a node into snapshot format with id.
buildNodeWithSN
buildNodeWithSN will build DOM from serialized node and store serialized information in the mirror.getMeta(node).
