From https://community.aseprite.org/t/slice-tool-issues/27705 some users might think the combobox is useful to rename the slice name, while the field is just a search/filter field, not sure what would be the best here, but we could:

1. Add a 🔍 icon to indicate this is a search field
2. If the Slice property dialog is non-modal the user could change the name of slices more quickly
