dsh-macos-tap-fix

A small workaround plugin for DeepSeek Harness (dsh / dsh-tauri) on macOS.

Temporary. Remove it once the WebKit fix ships.

Symptom

On macOS, with an input method (e.g. Japanese, Chinese) active and an editable element focused (such as the chat input), the first Tap-to-Click on a button does nothing; a second tap is needed. Pressing the trackpad down, or using Firefox, works.

Cause

WebKit Bug 219670: the tap's mouseup can be delivered before its mousedown, so the click is lost. A fix is proposed in WebKit/WebKit#76581. It affects Safari and WKWebView apps, including dsh-tauri.

What this plugin does

Browser-side only, macOS only. When a mouseup arrives with no preceding mousedown, it waits 40 ms; if no click reached that element, it dispatches one, and ignores the late mousedown. Normal clicks are untouched.

Install

In your dsh profile's package.json, add the dependency and the bundle, then restart the app:

"dependencies": { "dsh-macos-tap-fix": "github:lifwsp/dsh-macos-tap-fix" },
"dsh": { "profile": { "bundles": ["dsh-macos-tap-fix"] } }

To remove: delete both entries and restart.

Caveats

• It infers broken event order and synthesizes a click, so edge cases are possible. Use at your own risk.
• Only verified by hand on macOS 26.5.1 with Google Japanese Input.
• Plugins reload only after restarting the app.
