3730925 - App preview fails with "csrf token validation failed" in SAP Business Application Studio

Symptom

Previewing apps from BAS showing the following error messages:

Sorry, a technical error occurred! Please try again later.
\{
"message": "HTTP request failed",
"headers": [],
"statusCode": 403,
"statusText": "",
"responseText": "CSRF token validation failed"

While checking the http trace, it's found that in the response header of each HEAD request, the x-Csrf-Token value is a different one. And the POST request then failed with 403 error.

There's no issue while opening the same app which has been deployed in ABAP (for example).
