Research direction
No source file, test, or entry point is named. First reproduce the crash and memory growth on Windows 10 with WSL2, Ubuntu 18.04, Hyper 3.0.1, and zsh across four tabs, then collect the relevant logs or profiling data. Done means identifying the cause and confirming that four tabs no longer crash or cause excessive memory use.
