Such a problem was revealed.If you open the message for the first time, where the image is first proxy (or look through the preview), the image is displayed only on the second time you refresh the page.I thought at first that this was my modifications, but yesterday's clean test setup confirmed the problem.I accidentally saved the old file, the proxy, which I manually edited when I had 2.0.14.I do not remember where I took these edits, but with this file, everything is working fine for me
