Description

When the backspace key is pressed in an empty paragraph block or heading block, the block is deleted and the focus is shifted to the previous block. I think this is the expected behavior.

However, in WordPress 6.1(with or without Gutenberg ) if the block is preceded by a group or column, the block is not deleted, but wrapped in the previous block.

I think this is a bug, not an expected change.
