            Bug ID: 279356
           Summary: TypeError: Attempted to assign to readonly property -
                    extractFilteredSchemaValuesFromMicroData
           Product: WebKit
           Version: Safari 17
          Hardware: iPhone / iPad
                OS: iOS 17
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: DOM
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: loic at anicro.ch

Using Schema.org LocalBusiness #Example1 code with the microdata (https://schema.org/LocalBusiness#eg-0004)on a page makes Safari 17.5 with iPhone iOS 17 moo in the dev console with the following message: "TypeError: Attempted to assign to readonly property". 

Linked to native extractFilteredSchemaValuesFromMicroData and extractSchemaValuesFromSchemaOrg methods. 

This was reported on a real iPhone from a customer and reproduced with Xcode Simulator.

If needed here is a codesandbox (but copying example from schema.org is enough): https://codesandbox.io/p/sandbox/5tmwpr

Error has been reported multiple time since a couple of months at least here: https://github.com/odoo/odoo/issues/162145
