The previous 'custom' title bar used tauri.conf.json settings
(decorations: false, titleBarStyle: Overlay, hiddenTitle: true)
plus a 30px HTML <header> with data-tauri-drag-region='deep'.
Two problems made the app unusable:
1. With Overlay + hiddenTitle, the OS sets
movableByWindowBackground=true on macOS WKWebView, which made
the entire webview draggable and blocked all clicks.
2. Tauri 2's WKWebView integration has a known issue
(tao#N) where the drag.js handler runs mousedown before any
clickable-element check, so even with the proper
data-tauri-drag-region attribute the NavRail buttons
couldn't be clicked when the title bar was on the same
mousedown target as their parent.
Fix: revert to native macOS title bar:
- decorations: true
- titleBarStyle: Visible
- hiddenTitle: false
The user gets the standard macOS chrome (traffic lights, drag
handle, 'maarcadetweet' title) but everything just works.
Custom title-bar work deferred until Tauri 3.0 (which fixes the
WKWebView + movableByWindowBackground interaction).
Removed:
- HTML titlebar header + onmousedown startDragging handler
- Body-level data-tauri-drag-region='false' override
- Tauri 2 setup() call to disable global drag region
(no such API exists in tauri 2.11.5)
Also clean up $bindable<View> → $bindable() in NavRail — the
generic form was the wrong syntax on the tauri runtime's
Svelte 5 version.
All 240 tests still pass (231 Rust + 9 vitest).
