Description
Hi, I have found a reproducible markdown file that causes this weird scrolling issue. See attached md file.
You must ensure, the MacDown window is shorter than the distance between the two code blocks. The bug seems only to appear if both elements are not shown at the same time (-> make the window extra small during testing).
Also, if you remove the `# INJECT` comment, the bug will not appear. Here is a video:

Research direction
Open test-case.md in MacDown and reproduce the jump with the window shorter than the distance between the code blocks. Start by tracing the editor's scrolling behavior when the # INJECT comment is present, then verify that scrolling remains stable for the supplied case and that removing the comment still does not regress behavior.
