--readme option fails to select markdown files other than README.md in rubydoc.info

[xuan-cao-swi]

Not sure if this is the right place to ask, but hopefully I can get some insight from the YARD perspective and others who have had this issue.

Rubydoc.info seems always choose the README.md as the index, other than the markdown that --readme point at.

It's working on my local yard server (e.g. through yardoc; yard server)

Steps to reproduce

Here is my .yardopts

--no-private
--markup markdown
--readme yardoc_frontpage.md
lib/hola.rb
lib/hello.rb

and the yardoc_frontpage.md
