document.documentElement.innerText returns additional characters

[Lilyliu123]

Description
document.documentElement.innerText returns additional at the beginning of the returned string.

Open url http://date.jsontest.com using edge.
Go to inspect->console, run document.documentElement.innerText

Expected result:
'{\n "date": "08-22-2023",\n "milliseconds_since_epoch": 1692669570858,\n "time": "01:59:30 AM"\n}\n'
Actual result:
'1\n2\n3\n4\n5\n{\n "date": "08-22-2023",\n "milliseconds_since_epoch": 1692668052676,\n "time": "01:34:12 AM"\n}'

A "12345" was added at the beginning of the string which seems like the number of the lines of innerText.

For example, the url http://echo.jsontest.com/key/value/one/two, document.documentElement.innerText returns below:
'1\n2\n3\n4\n{\n "one": "two",\n "key": "value"\n}'

Version
Runtime: 116.0.1938.54
OS: Windows 10

Regression
Was this working before but has regressed? Yes
If yes, what version did this last work on? Runtime: 115.0.1901.203

Repro Steps
Open url http://date.jsontest.com using edge.
Go to inspect->console, run document.documentElement.innerText

Additional context
We got the issue first with our c# code:
CoreWebView2.ExecuteScriptAsync("JSON.parse(document.documentElement.innerText)").
The additional characters in the returned string broke the json format.
