rB8b7cd1ed2a17 broke this for the paint slots rB4669178fc378 broke this for regular attributes Name filtering in UI Lists works when: - [one] the items to be filtered have a name property -- see how `uilist_filter_items_default` gets the `namebuf` - [two] custom python filter functions (`filter_items`) implement it themselves -- if you use `filter_items` and dont do name filtering there, the default name filtering wont be used So, two problems with rB8b7cd1ed2a17: - [1] items to be listed changed from `texture_paint_images` to `texture_paint_slots` -- the former has name_property defined, the later lacks this - [2] the new `ColorAttributesListBase` defined a `filter_items` function, but did not implement name filtering And the problem with rB4669178fc378: - it added `filter_items` functions, but did not implement name filtering. These are all corrected now. Fixes T102878 Maniphest Tasks: T102878 Differential Revision: https://developer.blender.org/D16676
