Describe the feature

The Sticky Scroll feature works by automatically scrolling the file tree view such that your active file (the one you're currently working on or have selected) is always visible. This is highly useful because developers often deal with large codebases with nested file structures. Being able to keep track of your current file amidst the larger tree can help improve workflow and productivity, reducing the time to find and navigate between different parts of the codebase.

For reference there's a similar one for the code editor area: #5344
Both would be awesome!
