描述

Describe the bug

In Chrome, I lose the ability to scroll inside the Preview iframe after dragging the divider between the Preview iframe and the Sidebar on the left.

Below is a video "demonstrating" the problem. At the end, I attempt and fail to scroll vertically inside the Preview iframe, though in the video you can't tell that that's what I'm trying to do.

Reproduction link

https://stackblitz.com/github/storybookjs/sandboxes/tree/next/nextjs/default-ts/after-storybook

Reproduction steps

  1. Open Chrome. I'm using Chrome version 128.0.6613.120 (Official Build) (arm64), and my operating system is macOS 13.5.2.
  2. Go to https://stackblitz.com/github/storybookjs/sandboxes/tree/next/nextjs/default-ts/after-storybook
  3. In Storybook, navigate to a "Page" story (just so that the content in the Preview iframe is long enough for vertical scrolling).
  4. Click inside the Preview iframe; successfully scroll vertically.
  5. Resize the Preview iframe by dragging the divider between the Preview iframe and the Sidebar on the left.
  6. Attempt to scroll vertically inside the Preview iframe.

研究方向
The bug occurs after resizing the preview iframe by dragging the divider. The issue likely stems from the resizer component losing or not properly transferring scroll event listeners to the iframe after resize. Investigate the resizer component in the Storybook codebase, possibly in the addon essentials or core layout. Check the links to old issues (#1779, #2482, #17202) for previous fixes that might have regressed. The reproduction is clear via Stackblitz; use browser devtools to inspect event listeners on the iframe before and after resize.
