Instance Method Details

#ambiguous_new_block_position? ⇒ Boolean

HACK

This method returns whether we can reliably determine the position of the new block being added. This can be very difficult to generate due to possible resorting of blocks within a release combined with release previewing based on publishing time.

The only time this has caused an issue in use is adding a new first block, so this is used in combination with the above ‘new_block?` to decide whether to render the first block.

Returns:

  • (Boolean)
