这两句词典的例句,是垂悬结构吗?

老师,以下这两个例句,分别来自牛津类语词典和柯林斯词典,when从句的主语和ing分词短语的逻辑主语,都和主句的主语不同,请问它们都属于垂悬结构吗?如果是,词典中使用这种结构的句子,是否不太规范?

由主动句变成被动句后,原来的分词短语不受影响。所以,这不是垂悬结构,是因语态变换导致的。你再把它们变成主动句,试试。

The perspective of wheelchair users must be taken into account when designing public buildings.   

Looking still further ahead, by the end of the next century world population is expected to be about ten billion.
