Editorial: Clarification of Combobox Role and aria-haspopup Attributes (#2134)

Closes #2132

The current specification text has two separate paragraphs describing the aria-haspopup attribute value requirements on a combobox—which are essentially the same. These have a conflict on the MUST use of aria-haspopup that pops up a Listbox. The proposed amendment aims to merge these paragraphs to enhance clarity, ensuring a clear understanding between the role combobox and the aria-haspopup values.
