`open_stream()` allows control characters through the stream that affect the full output
Metadata
Current evaluation
Fixed terminal-style leakage from open_stream() by resetting styling on close in merged PR #444 (commit 2253735).
Resolution: closed resolved
Reason: Merged PR #444, commit 2253735, resets terminal styling when the open_stream() context closes, preventing ANSI sequences written to the stream from affecting subsequent output.

Issue body
### Bug Description
If you're using a stream from the emitter, it can send through control characters. This is mostly fine, except that these control characters can change (for example) the colour of the text output to the full system, and we never reset this.
### To Reproduce
Open a stream, send a control character (e.g. changing the text colour, `0;30`) to the stream, and then close the stream and print something else out.
