The German Affinity Publisher 1.7.3.481 on Windows behaves as follows (see attached video):
The document contains text with an image pinned as a character and an arrow plus legend pinned to flow with this image. Arrow and legend are positioned above the image.
At 0:04, I start typing additional text, so that the image with legend flows with the text nicely.
At 0:12, the image with legend correctly flows to the second page, which is nice. Unfortunately, now the Z order of the pinned objects is destroyed, so that arrow and legend are now behind the image, which is undesirable.
At 0:17, I repeatedly undo my actions, which unfortunately leaves the Z order scrambled.
The Z order can only be corrected by selecting the objects and manually bringing them in the foreground again.
This seems to happen with all objects pinned to the same position, but, just in case, the culprit is attached.
