Block types drupal hosting
Hi. I need a help with Drupal 8 templates, please.
I created a custom block, I can create a theme for the custom block (the instance), but I can't create a theme for the Custom Block TYPE (let's call it "the prototype").
I meant, is there a way to theming the different Custom Block Types?
And a "bonus question": Why in the Theme Debug I can see "block--block-content.html.twig" twice? Should I see one "block--block-content.html.twig" and one "block--CUSTOM-BLOCK-TYPE-content.html.twig"

I'm running Drupal 8.1 stable.

By default there is no way to theme custom content block bundles (type), however for Adaptivetheme I developed a way that you can, and you can implement this in your theme.
This would give you the block template: block--bundle--the-prototype.html.twig
I can't answer the bonus question, suppose it's a bug. Notice I use array_splice() to slot the template suggestion in the array rather than pushing it on the end and overriding the template for the instance.

- test on BlockContentInterface
- adding suggestion at the end instead of inserting
