WebKitGTK (Linux Tauri WebView) does not auto-dismiss the native
<input type="date"> popup after a value commit — the user has to
press Esc. Force-blur on change is a no-op on Edge Chromium WebView2
(Windows) and WKWebView (macOS), where the popup already closes.
Scope narrowed to /balance/snapshot per issue body. Six other date
inputs across the app share the same WebKitGTK bug; tracked in a
follow-up issue rather than bundled here.
Diagnostic: Ubuntu 24.04 + libwebkit2gtk-4.1-0 2.50.4-0ubuntu0.24.04.1.
