      NOTE: Here we attempt to handle synchronous XHR requests. Unfortunately,
      due to the fact that QNAM is both synchronous and multi-thread while KIO
      is completely the opposite (asynchronous and not thread safe), the code
      below might cause crashes like the one reported in bug# 287778 (nested
      event loops are inherently dangerous).

      Unfortunately, all attempts to address the crash has so far failed due to
      the many regressions they caused, e.g. bug# 231932 and 297954. Hence, until
      a solution is found, we have to live with the side effects of creating
      nested event loops.
