Web UI: WebAssembly is not defined when switching project folders #15327

Description

When switching between project folders in the Web UI, the page intermittently throws ReferenceError: WebAssembly is not defined from the marked library's WASM module.

Refreshing resolves it until the next folder switch. Reproduced on mobile PWA (iOS Safari, Android Chrome); likely not PWA-specific — may also affect desktop browsers.
