A line of many ` in fenced code breaks code block

[frantic1048]

While I'm trying to show a simple rST code sample, I found a line of ` will break Github-flavored markdown's fenced code block.

as this gist shows(please see raw text): https://gist.github.com/frantic1048/52ed865c4d0e078d3ae4

I tried same text on StackEdit.io, it does not break fenced code when meet line of , but break on line of three.

Is there anyway for escaping ?

Your external backticks need to be longer than the internal ones or you can use 3 (or more) tildes ~ for the beginning and end of the code block, for example:
