Testing xterm.js with WebGL Addon using Playwright

[mfasold]

I noted that xterm.js itself has some Playwright tests.

Unfortunately, I am not able to use Playwright for testing when using the WebGL Addon for xterm.js. Specifically, the page will not render correctly when opened in Playwright with Chromium or Firefox browsers (i.e. npx playwright open -b firefox [URL] ). It will render correctly with Playwright-Webkit. Furthermore, it renders correctly in when I do not load the WebGL Addon. And of course it renders correctly in all browsers without Playwright.

A minimal example would be to run ttyd /bin/bash (ttyd bundles xterm.js with WebGL and shares the terminal in the browser) and then npx playwright cr http://localhost:7681/.

This question might be better suited for the Playwright project, but I am hoping to get a pointer here since the Playwright tests are also run.
