Description

if there are many lines in the left side, and the lines are out of the screen, then if I scroll the left side of the screen in both upward and downward directions with two-fingure-guesture of the built-in touchpad of the APPLE MACBOOK, the macdown software seems jammed, and there is a resilience in the jamming zone.

如果左侧区域有很多行并超出屏幕，使用苹果笔记本自带的触控板手势（双指滚动）时，软件显示就像被卡住了一样，一弹一弹的。

Research direction
The issue reports a scrolling problem with the touchpad on MacBook, specifically in the left sidebar of MacDown. The bug occurs when many lines cause the sidebar to overflow, and two finger scrolling leads to a jamming effect. To resolve, one should examine the scroll view implementation in the left panel, likely using NSScrollView or NSTableView. Check for event handling of trackpad gestures and any potential conflicts with the main editor view. The repository is Objective C based, so looking at files like 'MPEditorView.m' or similar sidebar views is recommended. There are no linked PRs or assignees, and the issue has been open since 2016, so starting with reproduction on a current macOS version is necessary.
