Fix hash navigation logic

[Grafikart]

Fix how turbo handle hash navigation.

Issue

On my website I have links looking like this

<li><a href="#t0">00:00</a> Intro</li>

Here is how "href" behaves for such links

link.href  // http://localhost/courses/temporibus-accusamus-ullam-sed-5#t0' so it will never start with #
link.getAttribute('href') // '#t0'

With the fix, the navigation is not tracked by turbo, but navigating back to a known hash triggers a popstate event. So turbo logic need to be fenced to not be triggered.

I needed this change since my page contains an autoplay and a hash change make the video played multiple time. Like this issues #1017
