If you attempt to use an == check with lubridate intervals, it uses the interval duration, rather than the interval object itself.

Reading the docs for lubridate::interval, this doesn't seem like this should be the default behaviour. Shouldn't this act like comparing two time ranges?

library(lubridate)
> interval(start=ymd('2018-01-01'), end=ymd('2018-01-02')) == interval(start=ymd('2018-01-02'), end=ymd('2018-01-02')) 
[1] FALSE
> interval(start=ymd('2018-01-01'), end=ymd('2018-01-02')) == interval(start=ymd('2018-01-03'), end=ymd('2018-01-04')) 
[1] TRUE

Note, I am using lubridate 1.9.2
