## 2024-05-19 - Replace HTML disabled with aria-disabled="true" for Accessible Tooltips
**Learning:** Native HTML `disabled` attributes completely hide elements from screen readers and block all pointer/hover events, preventing tooltips from functioning for disabled elements.
**Action:** Replace `disabled` with `aria-disabled="true"`, enforce block click handlers via `e.preventDefault()`, and add a title tooltip directly to the element to maintain full tooltip accessibility and keyboard focus support for visually impaired and mouse users.
## 2024-08-14 - Accessible Tooltips for Icon-only Buttons
**Learning:** Icon-only buttons using only `aria-label` are accessible to screen readers, but sighted mouse users miss out on crucial context because no native tooltip is shown.
**Action:** Always add a `title` attribute matching the `aria-label` to icon-only buttons (like Zoom In/Out, Pagination, or Remove actions) to provide a native browser tooltip for mouse users.

Base UI React Button disabled native button tooltip disabled element documentation

πŸ’‘ Result:

In Base UI, the interaction between a Tooltip and a disabled element is governed by native browser behavior, where disabled elements do not fire mouse events (such as mouseenter or mouseover) [1]. Consequently, a Tooltip will often fail to trigger on hover when it is wrapped around a natively disabled button [1][2]. Key considerations and workarounds include: Native Limitation: When you use the disabled prop on a native button, the browser prevents the element from receiving pointer events [1]. Since Base UI's Tooltip relies on these events to trigger the popup, the tooltip will not appear [1]. Workaround: Pseudo-disabled state: To show a tooltip on a button that appears disabled, a common practice is to avoid the native disabled attribute on the trigger element [1]. Instead, you can use aria-disabled="true" to signal the disabled state to screen readers while keeping the element interactive (so it can still fire events like hover and focus) [1]. You must then manually handle the disabled logic in your onClick or other event handlers to prevent action when the button is "pseudo-disabled" [1]. Tooltip disabled Prop: Note that the disabled prop available on the Tooltip component itself (e.g., <Tooltip.Root disabled>) is intended to disable the tooltip functionality entirely, not to manage the disabled state of the trigger element [3]. Focus Behavior: Base UI has made updates to ensure that Tooltip.Trigger components that are explicitly marked as disabled (using the data-trigger-disabled attribute internally) do not open tooltips when focused, maintaining consistent behavior across different interaction types [4][5]. For robust, accessible design, if you need to provide information about why a button is disabled, the Base UI documentation suggests that an "infotip" patternβ€”using a Popover or a separate icon adjacent to the buttonβ€”is often superior to relying on tooltips for disabled elements, as it ensures all users (including touch users) can access the information [1].

In `@apps/desktop/src/features/score/ScoreView.tsx` at line 201, Ensure tooltips
remain available for disabled icon buttons by wrapping each affected button in a
tooltip-capable element, or use aria-disabled="true" with a guarded click
handler. Apply the fix at apps/desktop/src/features/score/ScoreView.tsx:201,
apps/desktop/src/features/score/ScoreViewer.tsx:297, and
apps/desktop/src/features/score/ScoreViewer.tsx:311, preserving each button’s
existing disabled behavior and titles.
