[Bug] Demo loads ~15s in Edge when Enhanced Security Mode is active

[Tom-Dynamsoft]

Reported Behavior

https://demo.dynamsoft.com/barcode-reader-js/ takes ~15 s to load in Edge 145 when Enhanced Security Mode (ESM) is active for the site. Disabling ESM brings it to ~5 s. Chrome loads the same page in 3–4 s. Reporter never manually enabled ESM — Edge auto-applied it.

Reproduction Steps

1. Open Edge 145.0.3800.58 (64-bit)
2. Navigate to the demo page
3. Toggle Enhanced Security via lock icon → site info panel
4. Compare load time: ESM ON ~15 s, ESM OFF ~5 s, Chrome ~3–4 s

Environment

Edge 145 (ESM ON)	~15 s
Edge 145 (ESM OFF)	~5 s
Chrome 144/145	~3–4 s
Test modes	Normal + InPrivate both affected

Root Cause

Edge ESM disables JIT, which severely impacts WASM execution. The DBR JS SDK is WASM-heavy. demo.dynamsoft.com is not on Microsoft's ESM trusted list, so Edge auto-restricted it.

Fix Approach

• Short term: detect ESM impact on page load and show a user notice with instructions to exempt the site
• Medium term: submit demo.dynamsoft.com to Microsoft's trusted site list
