Cannot open Kanban Board in Markdown mode

Describe the bug
While the markdown attribute plugin is activated there is no possibility to open a Kanban Board in markdown mode. Once I deactivate the markdown attribute plugin, I can do so without any problem

With Markdown-Attributes + Kanban Enabled:

 case 5:
                            return n = o.sent(),
                            this.file = null,
                            new EP('Failed to load "'.concat(e.path, '". ').concat(n.message)),
                            console.error(n),
                            [3, 6];


Exception: Failed to execute 'setAttribute' on 'Element': '"kanban-plugin":"basic"' is not a valid attribute name.

Without it, Kanban loads just fine. Is this an our plugin issue, @valentine195
