Comment (by isabel_brison):

 The `styles` property of `WP_Block_Type` should always be an array:
 https://github.com/WordPress/wordpress-develop/blob/trunk/src/wp-includes
 /class-wp-block-type.php#L269 but I'm not sure there are any safeguards
 against registering it as something else. It's always an array in core
 blocks, at least (I tried printing `$block_type->styles` just before that
 line and only arrays are output)

 I guess it won't hurt to check if it's an array before going into the
 `foreach` though.
