 I was using the Gutenberg editor prior to the 5.0.0 upgrade and was able
 to insert iframe and script tags via custom html blocks.  Now that I've
 upgraded to 5.0.X, I can no longer create a custom HTML block with iframe
 or script tags.  Is there a way I can change the way it's apparently
 stripping HTML tags from my custom HTML blocks?  I'm unsure if this issue
 is in the new codex or a problem with Gutenberg, so I'm submitted the
 ticket in both places.  This feels a little heavy handed, and incredibly
 odd and frustrating that this was working just fine prior to the
 "official" upgrade to use Gutenberg as the default editor.  As a web
 developer, I expect to have 100% control over things like "custom HTML
 blocks" without having the editor interfere.
