From 0bf0ed55c92f817fb09c9637a82d6ed9965a22d5 Mon Sep 17 00:00:00 2001 From: boomzero Date: Mon, 27 Jul 2026 09:04:51 +0800 Subject: [PATCH 1/5] fix: pin Monaco to 0.52.2 to stop intermittent load failures Monaco 0.53.0 declares its minified helper variables with `var` at the top level of every chunk file. AMD chunks are plain scripts rather than modules, so those helpers land on `window`: a live load leaks h, m, r, o, p, s, i, f, u, w, M, y and C. Different chunks give the same name different meanings -- `m` is the field-setter helper in language/css/monaco.contribution.js but is Object.defineProperty in yaml.contribution.6f43d486.js -- so whichever chunk script evaluates last wins. When yaml wins, the css chunk's `r(this, "_options")` call resolves to Object.defineProperty(this, "_options", undefined) and throws "Property description must be an object: undefined". The editor.main callback then never fires, ensureMonaco() times out after 30s, and submitpage.php falls back to the bare textarea. Evaluation order depends on network timing, which is why it only reproduces on some page loads. This is upstream microsoft/monaco-editor#5015, fixed in 0.54.0. cdnjs has no stable release newer than 0.53.0, and the rest of the script sources from cdnjs, so pin back to 0.52.2 -- it ships as a single bundle and leaks no globals at all. Also make ensureMonaco() single-flight. Overlapping callers (submit editor, merge view, freopen snippets) each appended their own loader.js, and the second loader resets the AMD registry while the first is still resolving modules. A failed load clears the cached promise so later calls can retry.
