Description
Currently, the up/down re-order buttons on a newly added block are disabled until focus lands on any block on the Story Builder.
Behaviour we want: re-order buttons to be enabled immediately when a new block is added.
Note: depending on the number of blocks added and their position, the re-order buttons may be appropriately disabled according to the design (i.e. if there is only one block added, both re-order buttons will be disabled, and the up button of the top block and down button of the bottom block will always be disabled).
