get_block_wrapper_attributes() not working in first preview

When using get_block_wrapper_attributes() inside a block template, the first time the block gets rendered in the preview, it throws an error:

> Trying to access array offset on value of type null

This is because WP_Block_Supports doesn’t have an initialized block.

This is a quick patch fix but probably the whole thing should be refactored to use native WP render methods no?
