when code end with space, mermaid.parse return true but mermaid.run throw error

[fengliner]

Description

if code end with space，run mermaid.parse(code) return true. But when run mermaid.parse({nodes: [ref.current]) throw error.

Steps to reproduce

const code = `
sequenceDiagram
    participant Alice
    participant Bob

    Alice->>Bob: 你好，Bob！
    Bob-->>Alice:
` + '  '

const html = <div ref={ref}>{code}</div>

when run mermaid.parse(code) return true. But when run mermaid.parse({nodes: [ref.current]) throw error.

when I read the source code of mermaid.run, I found that it will trim the space of code. It is the reason of the bug.
