Fixed:
- With two or more Item Slider blocks on a page, every slider but the last lost its Selection mode when the page was saved, and query sliders then showed nothing. With two or more Tabs (HTML) blocks, every block but the last lost its Default tab the same way. The page editor names each block's inputs only after the page has loaded, so until then the blocks' radio buttons formed one group and the browser kept only the last block's choice. Each block's radios now have a name of their own, and the saved value travels in a hidden field.
- A container's header in the page editor (Tabs (Blocks), Columns (Blocks)) showed the label of the first Tab / Section or Column inside it, e.g. "BlockSuite: Tabs (Blocks) — Now on view: Quiet Weather".
- Item Slider cards showed a linked resource, such as a Creator that links to an artist's item, as that item's URL. They show its title now, and a URI value shows its label.
