https://mermaid-js.github.io/mermaid-live-editor/ does work.
If you add an ENV var DEPLOY as true before building, svelte's config should pick it up and add a base path mermaid-live-editor

mermaid-live-editor/svelte.config.js

Lines 17 to 21 in 7c64a65

	paths: process.env['DEPLOY']
	? {
	base: `/mermaid-live-editor`
	}
	: {}
