Commit 1a0172a253e5432e5eef862768aaacb3463501f2 broke the display of buttons provided by plugins making use of the intranet_catalog_biblio_enhancements_toolbar_button hook. The addition of the html filter breaks the ability of the browser to parse the HTML provided by the plugin, the $raw filter needs to be used instead.
Created attachment 82700 [details] [review] Bug 21900: Fix erroneous filter Swap the filter from html to $raw. We need the browser to be able to parse the HTML supplied by plugins. Test plan: - Apply patch - Install plugin that uses the intranet_catalog_biblio_enhancements_toolbar_button hook, currently only https://github.com/PTFS-Europe/koha-plugin-cla-check_permissions/releases - View the /cgi-bin/koha/catalogue/detail.pl page for an record => TEST: Verify that the "CLA Check Permissions" button is displaying in the record's tool bar
Bug 21905 also addresses this problem and has a test plan involving the easier to test Kitchen Sink plugin. So I'm closing this one in favour of that one. *** This bug has been marked as a duplicate of bug 21905 ***
