scrollspy documentation bug? -- scrollspy requires that the spied anchor be visible

Created by: fczuardi

Sometimes, if the nav items links to page anchors that are set like:

<a id="anchor-id"></a>

The code will work on firefox but not on webkit (chrome and cordova apps for example).

The reason is because scrollspy use a jQuery is.(':visible') type of check, see https://github.com/twbs/bootstrap/commit/5a38a5775f8a3c58c09df0a0f3afc058c820c238

The workaround is to set display block on your anchors, like so:

<a id="anchor-id" style="display:block;"></a>
