request #20579: Better management of mermaid syntax error
When you enter an invalid diagram syntax, the mermaid diagram continuously display a spinner, without giving any clue to the end user. Example of such syntax: ```mermaid graph TD A A -->|Get money| B(Go shopping) ``` The proposal is to see if mermaid has produced a svg with error. This svg is not used because it does not give any useful information. If we detect such svg, then we assume that the error that is being thrown is containing syntax error details. It is then displayed below the source diagram. Change-Id: Iad7922e8c7a2175887fa29bcc1095616397c182f
