Of course CJ is correct that the mainstream is silent on this issue, which is the scandal just by itself, except of course, the first leaks were reported by Jonathan Steel, and Peter Hitchens in the Daily Heil.
MoA reckoned that this 4th set of leaks didn't substantially add to the known facts. See RT and MoA bits here:
What I find puzzling is that Russians didn't raise more stink about these leaks, although they did make statements questioning the OPCW reports, be it on Douma, Khan Sheikdoun, or Skripal case. These don't seem to get any traction in the MSM. The wall of silence is intact.
