.task-main is a flex column. Children default to flex-shrink: 1, so
when body content is taller than the available column height, flex
squeezes .preview-pane back to its min-height (200px) and the
overflow renders visibly on top of subsequent siblings — making the
TaskLogSection appear in the middle of the body content.
Surfaced by viewing a task with an unusually long markdown body in
preview mode. Pre-existed PR 1, just rarely hit.
NoteEditorView uses the standard block-flow .editor-main and isn't
affected.
