 When using title as orderby filter in REST API endpoint the I am getting
 wrong output.


 == Test cases: ==


 '''[Case -A]'''
 {{{#!php
 /wp-json/wp/v2/api/trips?filter[orderby]=title&order=asc&per_page=1
 }}}

 '''Desired output (post title):''' "Amritsar, the city of Golden Temple"
 '''Actual output (post title):''' "Auli Ski Resort"

 '''[Case -B]'''
 {{{#!php
 /wp-json/wp/v2/api/trips?filter[orderby]=title&per_page=1
 }}}

 '''Desired output (post title):''' "Amritsar, the city of Golden Temple"
 '''Actual output (post title):''' "Dharamsala - The deemed smart City"

 I did not specify any order as the default order in any query is supposed
 to be Ascending.

 '''[Case - C]'''
 {{{#!php
 /wp-json/wp/v2/api/trips?filter[orderby]=title&order=desc&per_page=1
 }}}


 '''Desired output (post title):''' "Sundarvans - the largest mangrove
 forest"
 '''Actual output (post title):''' "Dharamsala - The deemed smart City"

 To cross check I tested with other custom post type but here again REST
 API gave me wrong result.
