Also happens with JSON

This happens for me when in agent mode and Gemini tries to write a whole file, looks fine when it applies diffs.

I have this problem too. Everything is surrounded by back ticks and it took many prompts for me to realize Gemini is not aware of them, it does not know they are there. Also is happens whether I ask it to add to a file that I created, or a file it creates, regardless. It seems Gemini just doesn't work, everything gets surrounded by backticks that it's unaware of.

Fixed in #31439. Should be in Nightly already, and soon in Preview and Stable.
