Turbolinks causes a link with href="#" to trigger page refresh

I have a very simple link on my page. <a href="#">My link</a>. It causes a page refresh. when I remove "turbolinks", it no longer causes a refresh.

I've used links with hash fragments all the time in the past. Unless I've missed something very fundamental for a long time, I don't understand how this can cause a refresh.

It does not have any JS event handlers attached to it.

Any ideas?

It may not matter, but I'm using jQuery, Twitter-Bootstrap, and Ruby on Rails.

Clues so far:

• When I remove Turbolinks, the link behaves properly (does not cause page refresh).
• Links with "#" as the URL cause a reload on every page of my app.
• Links with any "#hasfragmenttext" will cause a single refresh and then the URL of the page is "mypage#hasfragmenttext", any additional clicks do NOT cause page refresh... hmm.

Use data-no-turbolink attribute on that link the error should be gone

<a href="#" data-no-turbolink>My link</a>
