axisFormat does not work for mermaid chart in DiagrammeR

[jbukszar]

Description

A simple example works fine, however, when I add axisFormat %m/%d/%Y, it returns text instead of a diagram.

Steps to reproduce

This one works when using mermaid in DiagrammeR:
library(DiagrammeR)
mermaid("
gantt
title A Gantt Diagram
dateFormat YYYY-MM-DD
section Section
First Task :a1, 2018-07-01, 30d
Another Task :after a1, 20d
section Another
Second Task :2018-07-12, 12d
Third Task : 24d
")

After adding line axisFormat %m/%d/%Y, I will get back only text instead of a diagram

mermaid("
gantt
title A Gantt Diagram
dateFormat YYYY-MM-DD
axisFormat %m/%d/%Y
section Section
First Task :a1, 2018-07-01, 30d
Another Task :after a1, 20d
section Another
Second Task :2018-07-12, 12d
Third Task : 24d

")
