Issue

HyperJS renders endline l and newline h markers on Windows and WSL. These disappear if you force a re-render by resizing the window. Neither WebGL nor Canvas rendering fix this issue.

Research direction

Reproduce the issue on Windows 10 with WSL using Hyper.app 3.2.3 and the linked .hyper.js configuration. Compare the initial rendering with a resize-triggered re-render, and test both WebGL and Canvas; done means endline l and newline h markers no longer appear during normal rendering.
