gpui: Unify track_scroll method to receive a reference type (zed-industries#43518)

huacnlee · web-flow · commit 1a23115773ac · 2025-11-26T18:03:42.000+01:00
Release Notes: - N/A This PR to change the `track_scroll` method to receive a reference type like the [Div#track_scroll](https://docs.rs/gpui/latest/gpui/trait.StatefulInteractiveElement.html#method.track_scroll), [Div#track_focus](https://docs.rs/gpui/latest/gpui/trait.InteractiveElement.html#method.track_focus). ```diff - .track_scroll(self.scroll_handle.clone()) + .track_scroll(&self.scroll_handle) - .vertical_scrollbar_for(self.scroll_handle.clone(), window, cx) + .vertical_scrollbar_for(&self.scroll_handle, window, cx) ``` https://github.com/zed-industries/zed/blob/56a2f9cfcf0c6a3c38f596b58002953763cd890f/crates/gpui/src/elements/div.rs#L1088-L1093 https://github.com/zed-industries/zed/blob/56a2f9cfcf0c6a3c38f596b58002953763cd890f/crates/gpui/src/elements/div.rs#L613-L620
