Description

Support for ::before and ::after pseudo-elements would be amazing!

Was reading up on current support for pseudo-selectors and taking a look at https://github.com/airbnb/enzyme/pull/1537, and supporting ::before and ::after would be much appreciated.

Contributor guide

Research direction
Investigate how other testing frameworks support pseudo elements. Review linked PR #1537 for previous attempts and discussion. Examine enzyme's source code, particularly the rendering logic in src/render and selector handling in src/selectors. Determine if a simulation of pseudo elements is feasible within enzyme's shallow rendering or if it requires deeper integration with React's test renderer.
