From 9f8b8cf84b0a2643579f168add697b2e3188d506 Mon Sep 17 00:00:00 2001 From: Paddy Mullen Date: Sat, 21 Feb 2026 16:32:20 -0500 Subject: [PATCH 1/2] fix: WASM marimo test checks rendered markdown instead of anywidget The anywidget rendering pipeline does not complete in Pyodide/WASM, so the test now verifies that the marimo React app boots, Pyodide initialises, and the Python-generated markdown cells render correctly. Timeout increased to 180s to accommodate slow Pyodide startup.
