In the “All categories” dropdown input, if you hover your mouse over any category title it will display a tooltip containing the category’s description.
However, if you hover your mouse over the counter beside the category title, the tooltip will also contain any HTML in the description + the ellipsis HTML entity.
Yes this is mostly due to how categorybadge works, we should really improve this. It has its own logic which comes clashing with any parent component which wants to show a title too.
I feel like category badge should be able to express a structure without markup.
