Split attributes on paste — available for all users today

When adding a custom attribute, you can now paste a full name=value string directly into the attribute field, and it will automatically split into the correct name and value fields for you. This enhancement removes a repetitive manual step for adding custom attributes, so all you have to do is paste once to get both fields populated correctly.

Pasted attributes are also validated automatically. If your attribute is a duplicate of an existing attribute or contains invalid characters, you’ll see a clear error message.
