### Dify version

1.16.1

### Cloud or Self Hosted

Self Hosted (Docker)

### Steps to reproduce

Steps to reproduce:
1. Fresh install of Dify v1.16.1 via Docker Compose in an **offline environment** and clear browser cache.
2. Create a chatflow in an **older browser** version. It can be edited normally, but cannot be published. (The console shows WASM and publish errors, as shown in Figure 1.)
3. Open the same chatflow in a **newer browser** version. A "Syncing data, just a few seconds" prompt keeps blocking the interface, making it impossible to perform any operations. (as shown in Figure 2)

Notes:
- **Older Browser UA**: `Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/106.0.0.0 Safari/537.36`
- **Newer Browser UA**: `Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.0.0 Safari/537.36 Edg/122.0.0.0` and `Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/150.0.0.0 Safari/537.36`

### ✔️ Expected Behavior

The chatflow should be editable and publishable normally.

### ❌ Actual Behavior

Editing a chatflow in an older browser results in a console WASM error and prevents publishing. In a newer browser, the 'Syncing data, just a few seconds' prompt blocks the interface, disabling all interactions.

Reproduce the issue with a fresh Dify v1.16.1 Docker Compose install in the specified older and newer browser versions, with the environment offline and the browser cache cleared. Start by inspecting the console WASM and publish errors, then trace the source of the persistent “Syncing data, just a few seconds” notification. Done means the chatflow remains editable and can be published in both browser versions.
