Cannot save Markdown gist with Mermaid Diagrams

[amirmishani]

Describe the bug
Can't save markdown gist when using mermaid charts. The saving process is stuck in an infinite loop and I see the following in the VS Code status bar:

Saving 'readme.md': Writing into file...

To Reproduce
Steps to reproduce the behavior:

1. Create a new markdown gist
2. Add the following code

```mermaid
graph TD;
    R[Root Module]-->A[Module A];
    R-->B[Module B];
    A-->C[Module C];
    A-->D[Module D];
    A-->E[Module E];
    B-->E;
```

3. Try to save

Expected behavior
Should be able to save the file.

Desktop (please complete the following information):

• VS Code Version v1.104.3
• GistPad Version v0.9.5

Additional context
There should be no issues with the code since I'm able to quickly save the file directly on Github Gists site.
