Checklist

• [x] I have searched the issue list
• [ ] I have tested my example against Shopify Liquid. (This isn't necessary if the actual behavior is a panic, or an error for which IsTemplateError returns false.)

Expected Behavior

Hello, Bob Orange!

Actual Behavior

Hello, 123!

Detailed Description

text := "Hello, {{ 123 }}!"
bindings := map[string]string{
    "123": "Bob Orange",
}
lqEngine.ParseAndRenderString(text, bindings)
