Actionbar text rendering error after resource‑pack reload in snapshot 25w16a

In snapshot 25w16a, whenever I reload resource packs (e.g. by pressing F3+T), the Actionbar text often displays layer compositing issues: the top and bottom text layers are incorrectly blended, causing characters to overlap.

• Expected: Actionbar text should render with correct layer compositing, with both layers perfectly aligned and no visual artifacts.

• Actual: After reload, the text layers fail to composite properly—characters from different layers overlap.
