描述

Thank you for #123.

But having the new option affect all events goes a little far for my use case. Now if I set preventMouseEventsDefault: false, I scroll the screen when trying to pan via touch or zoom with the mousewheel.

Is there a way to prevent this?

研究方向
Investigate the current implementation of event handling in the library, specifically how options like `preventMouseEventsDefault` are applied. The goal is to add a separate option to disable `preventDefault()` only for click listeners without affecting scroll/pan behavior. Review the codebase for event listener registration (likely in `src/svg pan zoom.js` or similar). Consider adding a new boolean option, e.g., `preventClickDefault`, and modify the click event listener to conditionally call `preventDefault()`. Ensure backward compatibility with existing options. Reference the existing PR #123 for context on the original change.
