Полина bc6095f2c0 editor: Fix buffer header context menu line height in multibuffers (#61923) ... ## Objective Right-clicking a buffer header in a multibuffer showed a context menu whose item spacing did not match other context menus. The menu is drawn via a deferred draw, which inherits the editor's text style stack, so its line height followed `buffer_line_height` instead of the default UI line height. This is the same root cause as #24504, which #25172 fixed for the editor's mouse context menu and completion popovers. The buffer header menu was a remaining call site. ## Solution `ContextMenu` now applies the default (`comfortable`) line height itself in `render`, next to its existing rem size and font family normalization, so menus render the same regardless of where they are opened from. This fixes the all workarounds and the need for them too: the workaround in `layout_mouse_context_menu` is removed, and the buffer header ends up needing no changes at all. The completions and code actions popovers keep their override in `element.rs`: they are not `ui::ContextMenu`s and compute their sizes with eager `window.line_height()` reads while being built, so styling on the elements they return cannot cover them. Migrating them could be a follow-up. ## Testing - `cargo check --workspace` passes, `./script/clippy` on the touched crates passes. - Manual: set `"buffer_line_height": "standard"` (or any extreme custom value to see it better), open a multibuffer (e.g. project search), right-click a buffer header, and compare the menu with another context menu (e.g. a tab's) — spacing matches. The editor's mouse context menu, which lost its own override, renders as before, and with default settings there is no visual change anywhere. - Tested on macOS, change is platform-independent styling. ## Self-Review Checklist: - [x] I've reviewed my own diff for quality, security, and reliability - [x] Unsafe blocks (if any) have justifying comments - [x] The content adheres to Zed's UI standards ([UX/UI](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) and [icon](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md) guidelines) - [ ] Tests cover the new/changed behavior (visual styling fix; menu text styles have no existing test coverage) - [x] Performance impact has been considered and is acceptable ## Showcase Regular context menu: <img width="425" height="164" alt="A context menu elsewhere in the app, showing normal item spacing" src="https://github.com/user-attachments/assets/1fc13981-b394-444f-883a-ce3ef462c386" /> Before: <img width="425" height="164" alt="Buffer header context menu before the fix, with tighter item spacing following the custom buffer_line_height" src="https://github.com/user-attachments/assets/9774076c-7e0c-41dd-b54f-53de58b24336" /> After: <img width="425" height="164" alt="Buffer header context menu after the fix, with item spacing matching other context menus" src="https://github.com/user-attachments/assets/ae76e37c-8e39-474c-8a5e-e229e69173fb" /> --- Release Notes: - Fixed the file header context menu in multibuffers not matching other context menus' spacing when a custom `buffer_line_height` is set. --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> Co-authored-by: zed-zippy[bot] <234243425+zed-zippy[bot]@users.noreply.github.com>		2026-08-16 11:41:17 +00:00
