Base UI React 1.5.0 Tooltip Trigger render custom element focus keyboard combobox highlighted item input focus

💡 Result:

In Base UI React **1.5.0**, `Tooltip.Trigger` can render a custom element via `render`, but it still opens on **focus or hover of that rendered element**. The version’s implementation attaches focus/hover handlers and defaults to rendering a `<button>`. ([raw.githubusercontent.com](https://raw.githubusercontent.com/mui/base-ui/v1.5.0/packages/react/src/tooltip/trigger/TooltipTrigger.tsx))

For a combobox, keyboard navigation typically **highlights** an item while focus stays on the input; highlighting alone does not focus the item. So a tooltip trigger rendered as a combobox item won’t open from keyboard highlighting unless that item actually receives focus. **Don’t move focus off the input** just to show its tooltip; instead, control the tooltip’s open state from the combobox’s highlighted-item state. The current Combobox docs describe a callback for highlighted-item changes, but I haven’t verified that API against 1.5.0. ([base-ui.com](https://base-ui.com/react/components/combobox?utm_source=openai))

The 1.5.0 source confirms custom rendering and focus handling; it does not establish that `Tooltip.Trigger` reacts to combobox highlight state automatically. ([raw.githubusercontent.com](https://raw.githubusercontent.com/mui/base-ui/v1.5.0/packages/react/src/tooltip/trigger/TooltipTrigger.tsx))

raw GitHub mui base-ui v1.5.0 packages/react/src/combobox keyboard highlighted item input focus active descendant

💡 Result:

In **Base UI v1.5.0**, the Combobox uses **virtual focus**: keyboard navigation updates the highlighted item while focus stays on the input, rather than moving DOM focus to each option. The root wires Floating UI’s list navigation with `virtual: true`; arrow-key navigation updates the active index, and the item’s `highlighted` state reflects that index. ([raw.githubusercontent.com](https://raw.githubusercontent.com/mui/base-ui/v1.5.0/packages/react/src/combobox/root/AriaCombobox.tsx))

When an item is highlighted, the input exposes it as the active descendant via the navigation props merged into its props. The source doesn’t contain the literal string `aria-activedescendant`—that attribute is supplied by the list-navigation implementation. Typing clears the highlight when `autoHighlight` is off, which returns virtual focus to the input; with auto-highlight enabled, the first match can be highlighted instead. ([raw.githubusercontent.com](https://raw.githubusercontent.com/mui/base-ui/v1.5.0/packages/react/src/combobox/root/AriaCombobox.tsx))

Pressing **Enter** selects the highlighted item without focusing it first: the input handler clicks the item at the active index. ([raw.githubusercontent.com](https://raw.githubusercontent.com/mui/base-ui/v1.5.0/packages/react/src/combobox/input/ComboboxInput.tsx))

Expose the full project label for the highlighted row.

Base UI 1.5.0 uses virtual focus for combobox navigation. Keyboard navigation highlights a row while focus remains on ComboboxSearchInput. The span tooltip trigger therefore does not receive focus, so its focus-or-hover tooltip does not open. A truncated label can remain visually unavailable to keyboard users. Expose the full label for the highlighted row instead of moving focus from the input.

Review comment at @apps/web/src/components/chat/DraftHeroHeadline.tsx at line
338:
Update the tooltip behavior in the highlighted-row rendering near TooltipTrigger
so keyboard navigation exposes the full project label while focus remains on
ComboboxSearchInput; do not rely on the span receiving focus or move focus away
from the input.
