Tabs & subgraphs cause rendering error

[nayrangnu]

I spent a long time trying to figure out why my code was not rendering after I tried adding a subgraph. Eventually, I realized that using spaces instead of tabs makes it render. Perhaps something in the subgraph code?

I had the same issue.

graph TB
   subgraph One
      a1-->a2
   end

This will not compile for CLI either if there are tabs instead of spaces for the indentation. Using mermaid 6.0.0 and phantomJS 2.1.1

I confirm that it is an issue. Tabs doesn't work.

No syntax error but there is also no output chart.

It seems that this issue only happens with subgraph. There is no problem if no subgraph: https://mermaidjs.github.io/mermaid-live-editor/#/edit/Z3JhcGggVEIKCWExLS0-YTIK
