## Dependency updates - `@elastic/eui` - v114.3.0 ⏩ v115.0.0 - `@elastic/eslint-plugin-eui` - v2.11.1 ⏩ v2.12.0 ## Package updates ### Summary > [!NOTE] > Please be mindful that as the Design System team we are not aware of your specific area pre-requisites and testing setups, and are realistically not capable of testing the entirety of Kibana. That being said, we want to do our best at migrating breaking changes. All tooltip usages were updated accordingly but there might be mistakes and bugs. That's why, **I would advise every reviewer to smoke-test their domain tooltips**. We'd also greatly appreciate your help with adjusting anything that may be wrong 🙏🏻 https://github.com/user-attachments/assets/2da29c89-aba1-40f9-ae3e-13790a34aedf - tooltips **no longer appear on programmatic focus return** (e.g. when closing flyouts, modals) - unless you're using the keyboard to navigate, - tooltips **do not persist on mouse click** which was annoying for the sighted users and tricky to handle in automated testing environments, - there's **no timeout-based delay** that's inconsistent across Kibana and makes the UI seem laggy, - we made the **animation simpler** and tooltip content **font-size smaller**, resulting in a better visual hierarchy, -VoiceOver no longer has problems with **announcing tooltip content** on trigger focus. These changes have been developed with [SC 1.4.13 Content on Hover or Focus](https://www.w3.org/TR/WCAG21/#content-on-hover-or-focus) in mind while providing the best possible UX. ### `@elastic/eui` [v115.0.0](https://github.com/elastic/eui/blob/main/packages/eui/changelogs/CHANGELOG_2026.md) - Updated `EuiToolTip` default font size from 14px to 12px ([#9627](elastic/eui#9627)) - Updated `EuiToolTip` show animation to opacity-only with a 150ms grace period delay, preventing visual flickering when quickly hovering over multiple tooltip triggers ([#9626](elastic/eui#9626)) - Updated `EuiToolTip` to respect input modality. Tooltip no longer persists on mouse-click focus or shows on programmatic focus return. ([#9624](elastic/eui#9624)) **Bug fixes** - Fixed `uiPlugins[].button` type to allow UI plugins to not have a toolbar button in `EuiMarkdownEditor` ([#9634](elastic/eui#9634)) - Fixed `EuiToolTip` self-hiding when the mouse moves over child elements within the trigger ([#9626](elastic/eui#9626)) **Breaking changes** - Removed `delay` prop and `ToolTipDelay` type from `EuiToolTip` and `EuiIconTip` ([#9626](elastic/eui#9626)) - Removed `waitForEuiToolTipVisible` and `waitForEuiToolTipHidden` RTL test helpers; tooltip show/hide is now synchronous so direct assertions can be used instead ([#9626](elastic/eui#9626)) **Accessibility** - Fixed invalid nested interactive elements in `EuiMarkdownEditor` by removing `role` from the drop zone wrapper. ([#9625](elastic/eui#9625)) ### `@elastic/eslint-plugin-eui` [v2.12.0](https://github.com/elastic/eui/blob/main/packages/eslint-plugin/changelogs/CHANGELOG_2026.md) - Added a new `prefer-tooltip-trigger-focus-test-utility` rule that flags `fireEvent.focus()` inside `it`/`test` blocks that also query for a tooltip. The rule auto-fixes to `focusEuiToolTipTrigger` from EUI's RTL test utilities. ([#9624](elastic/eui#9624)) --------- Co-authored-by: kibanamachine <42973632+kibanamachine@users.noreply.github.com>
