Low priority.
In 84b3172 we changed embedded link and image render hook enablement from booleans to enums. When set to "always" we override custom hooks with the names "render-link.html" and "render-image.html". This is sufficient for (I would guess) 95% of sites, if not more.
However, the override logic does not work for custom hook template names with higher specificity such as:
render-image.html.html
render-image.en.html
render-image.en.html.html
- and maybe others that I'm not thinking of at the moment.
I'm not sure we should even do something about this, but wanted it logged.
