Non English native speaker warning!
Actually, the UML standard decide to use hollow arrow represent the asynchronous message in Sequence diagram.
But you haven't add this kind of arrow in your greate artwork mermaid.
I bring up this little flaw to help you perfect mermaid.

I will be adding this in version 8.9.0.

The syntax will be --) for a dotter version and -) for a solid arrow.

Example:

 sequenceDiagram
	  Actor1 -) Actor2:Async
	  Actor1 --) Actor2:Async dotted
	  Actor1 ->> Actor2:Sync
	  Actor1 -->> Actor2:Sync dotted

Renders like this:
