<a href="about:blank">link</a>
the OnBeforeBrowse will not be called, so it is not possible to cancel the navigation to an empty page.
I believe that it's a bug, not a feature

OnBeforeBrowser not raised for about:blank
by arvelius » Tue May 15, 2018 3:37 am
When clicking on a link like
<a href="about:blank">link</a>
the OnBeforeBrowse will not be called, so it is not possible to cancel the navigation to an empty page.

How about returning RV_CANCEL in OnBeforeResourceLoad?
