JSON mode glitches out when asked to make a codeblock in markdown

[Visual-Studio-Coder]

Description of the bug:

The response stops generating randomly, and causes an incomplete JSON to be formed.

Actual vs expected behavior:

It says something like

"What is the following code supposed to do?\n\n"

instead of "What is the following code supposed to do?\n\njava System.out.print("helloworld");"

It just stops generating the prompt for some reason. this is also recreatable in the AI Studio

Any other information you'd like to share?
