説明

Let's say you want to move a file from a directory to another in the Files view, but the target directory is outside of the view, meaning you would need to scroll down. In most UIs, bringing the dragged element near the bottom edge of the screen would slowly scroll down, allowing you to reach the target directory. Alternatively, using the mousewheel while dragging could work too.

Neither of them works in Theia (tested on Chromium on Linux), meaning it's very difficult to move a file to a directory that is outside of view.

調査方針
The Files view implementation is likely in the 'packages/files' directory of the Theia repository. Look for drag and drop event handlers in the file tree widget (e.g., 'file tree.ts' or similar). The auto scroll behavior can be implemented by checking the mouse position relative to the widget's bounding box during drag and programmatically scrolling. Refer to the existing drag implementation and add scroll on drag functionality. The issue is from 2018; verify if any changes since then have affected this behavior.
