Describe the bug Some flowchart examples from Mermaid website are not working in Typora. More specifically the direction statement results in error. If I remove the statement, the graph shows correctly.

To Reproduce Steps to reproduce the behavior:

Create a new document
Create a mermaid code block

Paste the following code:

flowchart LR
subgraph TOP
direction TB
subgraph B1
    direction RL
    i1 -->f1
end
subgraph B2
    direction BT
    i2 -->f2
end
end
A --> TOP --> B
B1 --> B2

See the error being shown as follows:

ERROR: [Mermaid] Parse error on line 3:
...h TOP    direction TB    subgraph B1 
----------------------^
Expecting 'SEMI', 'NEWLINE', 'EOF', 'AMP', 'START_LINK', 'LINK', got 'ALPHA'

Expected behavior The mermaid diagram should be shown correctly
