Mermaid Live Editor can't handle more than 1200 lines

[Az8th]

I don't know if this is intended, but it makes the Live Editor unable to handle big flow charts.
It crashes (page goes white) everytime I wrote the 1200th line, whatever the content of the file.

I tested with Firefox and Chrome on multiple computers : same behaviour.
Here is an example file:
