HooglyBooglyAuthorUnsubmitted Done Inline Actions Sorry for putting this in here, it was related at one point developing these changes but not anymore. Originally I thought I had to remove the block immediately when the panel was removed, but we can just leave it and it will be removed later by `ED_region_do_draw` and the like. Removing it is nice because it reduces reliance on the somewhat hacky `UI_list_panel_unique_str` and results in fewer unnecessary string lookups. I can commit this separately.
