What went wrong?
1. Setting location.hash with value previously set
2. The page isn't scrolled

Summary of issue:
Setting location.hash doesn't scroll the page and update the sequential focus navigation starting point (https://developers.google.com/web/updates/2016/03/focus-start-point) when the new and old value are same.

- Chrome has this issue
- Firefox and Edge don't have this issue (the page is scrolled and the sequential focus navigation starting point is updated)

Activating internal links (intra-page links) always scroll the page and update the sequential focus navigation starting point when the new and old hash are same.

- Chrome, Firefox, and Edge works fine.

Expected behavior:
Setting location.hash should scroll the page and update the sequential focus navigation starting point regardless of value.

Without this issue, developer can write following code:

<div id="page"><!-- the content goes here --></div>
<button type="button" id="button">The content will be refreshed. Please read from the beginning of the page.</div>
<script>
document.getElementById('button').addEventListener('click', () => {
	// refreshing the content...

	// Navigate user to the beginning
	location.href = 'page';
}, false);
</script>

However, with this issue authors need to write a bit complicated script.

<div id="page"><!-- the content goes here --></div>
<button type="button" id="button">The content will be refreshed. Please read from the beginning of the page.</div>
<script>
document.getElementById('button').addEventListener('click', () => {
	// refreshing the content...

	// Navigate user to the beginning
	var el = document.getElementById('page');
	el.scrollIntoView(el);
	el.focus();
	// focus() fails silently
	// there is no simple cross-browser way to identify whether the element is focusable or not.
	if (document.activeElement !== el) {
		el.tabIndex = -1;
		el.focus();
	}
}, false);
</script>
