When you have a block among many other blocks, copy block as embedded is source page, paste as embedded in destination page. In destination page move the position of this block a few blocks up or down (among other blocks). Notice what happens in source page. Its position in source page was also changed.

After restart it didn’t occur. So I tested again. Follow above steps and if it is ok then change the position of the source and remember between which block of text it is placed. After that go to the destination and change the position up or down. Than the position of source should change.
In both source and destination pages I moved blocks with Shift+Alt+↓.
