VScode insiders can't fully show the output image 😢🥺

[Andtise]

Background

I am using Vscode insiders to use copilot chat. it's perfect for me!
my VScode version is 1.79.0-insider. But it can't show the output image fully. I am puzzled by it.

Problem

Here is a screenshot of the problem：

You can see that the output image just shows one line height.

And the same file shows right in the old version of vscode:

P.S. I haven't run the kernel, and the image is the output of the last run.

Thinking

I don't know if this is a bug or a setting issue. But the older version of vscode for my preview version is the same setup.
