After I upgraded our instance from 2.9.0-beta.5 to 2.9.0-beta.9, our custom override of the pinned banner is no longer working. I’ve tried out the other examples listed in Developer’s guide to Discourse Themes and while the plugin outlets still work, overriding entire handlebars themes does not work.
To reproduce, include something like this in your theme custom html/css
<script type="text/x-handlebars" data-template-name="components/discourse-banner">
<div style="height: 25px; width: 25px;background: red"></div>
</script>
which should replace the banner with a red box. However, nothing happens.
I’d appreciate any help to debug this further
