@startuml or @startgantt stops toc generator from functioning. #60
Description
I am using plantuml code blocks, like so...
```plantuml
@startuml
start
:Init Phase;
:Transfer Phase;
note right
long running activity,
process requires signal to proceed
end note
:Termination Phase;
stop
@enduml
```
Or, this:
```plantuml
@startgantt
skinparam monochrome true
[Task1] on {Alice} lasts 8 days
then [Task2] on {Bob} lasts 4 days at 50%
then [Task3] on {Carol} lasts 2 days at 25%
@endgantt
```
Either of these stop the TOC generator from functioning. In the first example, I can workaround by removing the @startuml and @enduml markers. However, in the second example, I cannot, because that's a critical part of the syntax.
It's as though the TOC generator is not really treating the code block as fully code. It seems something about the "@" syntax is throwing off the processing.
I'm not sure if there is any sort of error log I might be able to find to help narrow down the problem.
