Xpath not working with Edge 138 + driver 138.0.3351.83 on Windows Server 2022

[jochen-testingbot]

Hi,

We are looking into an issue where for example //*[@id='dropdownLanguageButton'] is not working (no elements found):

COMMAND FindElement {
   "using": "xpath",
   "value": "//*[@id='dropdownLanguageButton']"
}

Full log output: debug.txt

This is working correctly with Edge 137, but seems broken with Edge 138.

When comparing the edgedriver logs between these two, we see Runtime.callFunctionOn being called when it does work.

Runtime.callFunctionOn (id=24) (session_id=070214A5C56C00F8C91BC882D27CFA3B) DDC01D3FF604EE2DABA4E727B36C6FFD {
   "arguments": [  ],
   "awaitPromise": true,
   "functionDeclaration": "function(){ return (function() { // Copyright 2012 The Chromium Authors\n// Use of this source code is governed by a BSD-style license that can be\n// found in the LICENSE file.\n\n/**\n * Enum for WebD...",
   "serializationOptions": {

   },
   "uniqueContextId": "827088815372103342.6457104223119823620

But not called when it does not work (Edge 138).

This is how we start:

   "capabilities": {
      "firstMatch": [ {
         "browserName": "MicrosoftEdge",
         "browserVersion": "138",

            "binary": "D:\\edge\\138\\msedge.exe",
            "prefs": {
               "user_experience_metrics.personalization_data_consent_enabled": true
            }
         },
         "platformName": "windows"
      } ]
   },

Thanks!
