When swapping the position of two flow blocks after modifying their name (on the pagelayout edit), it is possible that the two block names will be wrong - that is, the block contents will swap but their names will remain in the previous position.
1. Create two different flow blocks on a page. Give Them a different Name each (Block A - Name A, Block B - Name B)
2. Save the page
3. Edit the page
4. Change the Names of the Blocks ("Name A" -> "Name A2", "Name B" -> "Name B2")
5. Click on the Arrow down on Block A to move it behind Block B, or vice-versa.
6. The blocks are changed, but not their names.
Block B - Name B2
Block A - Name A2
Block B - Name A
Block A - Name B
This behavior is not observed every time, but seems to occur with some consistency when blocks are moved while ezautosave is saving the new block name(s).
