`v89.1.0`⏩`v90.0.0`

The majority of changes in this PR come from:

- **EuiContextMenu** being converted to Emotion
(elastic/eui#7312). If your usage of
`EuiContextMenu` was significantly affected, we recommend pulling down
this PR and QAing it locally.

- `defaultProps` being removed from some very widespread components,
particularly **EuiButton**, in anticipation of React's upcoming
deprecation.

## [`90.0.0`](https://github.com/elastic/eui/tree/v90.0.0)

- Updated the `eventColor` prop on `EuiCommentEvent` to apply the color
to the entire comment header.
([#7288](elastic/eui#7288))
- Updated `EuiBasicTable` and `EuiInMemoryTable` to support a new
controlled selection API: `selection.selected`
([#7321](elastic/eui#7321))

**Bug fixes**

- Fixed controlled `EuiFieldNumbers` not correctly updating native
validity state ([#7291](elastic/eui#7291))
- Fixed `EuiListGroupItem` to pass `style` props to the wrapping `<li>`
element alongside `className` and `css`. All other props will be passed
to the underlying content.
([#7298](elastic/eui#7298))
- Fixed `EuiListGroupItem`'s non-transitioned transform on hover/focus
([#7298](elastic/eui#7298))
- Fixed `EuiDataGrid`s with `gridStyle.stripes` sometimes showing buggy
row striping after being sorted
([#7301](elastic/eui#7301))
- Fixed `EuiDataGrid`'s `gridStyle.rowClasses` API to not conflict with
`gridStyle.stripes` if dynamically updated
([#7301](elastic/eui#7301))
- Fixed `EuiDataGrid`'s `gridStyle.rowClasses` API to support multiple
space-separated classes
([#7301](elastic/eui#7301))
- Fixed `EuiInputPopover` not calling `onPanelResize` callback prop
([#7305](elastic/eui#7305))
- Fixed `EuiDualRange` incorrectly positioning highlights when rendered
with `showInput="inputWithPopover"`
([#7305](elastic/eui#7305))
- Fixed `EuiTabs` incorrectly wrapping text when it should instead
either scroll or truncate
([#7309](elastic/eui#7309))
- `EuiContextMenu` now renders text colors correctly when used within an
`EuiBottomBar` ([#7312](elastic/eui#7312))
- Fixed the width of `EuiSuperDatePicker`'s Absolute date picker
([#7313](elastic/eui#7313))
- Fixed `EuiDataGrid` cells visually cutting off overflowing content a
little too quickly ([#7320](elastic/eui#7320))

**Deprecations**

- Deprecated `EuiBasicTable` and `EuiInMemoryTable`'s ref `setSelection`
API. Use the new `selection.selected` API instead.
([#7321](elastic/eui#7321))

**Breaking changes**

- Removed `EuiPageTemplate_Deprecated`, `EuiPageSideBar_Deprecated`, and
`EuiPageContent*_Deprecated`
([#7265](elastic/eui#7265))
- Removed the `ghost` color option from `EuiButton`, `EuiButtonEmpty`,
and `EuiButtonIcon`. Use an `<EuiThemeProvider colorMode="dark">`
wrapper and `color="text"` instead.
([#7296](elastic/eui#7296))

**Dependency updates**

- Updated `refractor` to v3.6.0
([#7127](elastic/eui#7127))
- Updated `rehype-raw` to v5.1.0

**Accessibility**

- `EuiContextMenu` now correctly respects reduced motion preferences
([#7312](elastic/eui#7312))
- `EuiAccordion`s no longer attempt to focus child content when the
accordion is externally opened via `forceState`, but will continue to
focus expanded content when users click the toggle button.
([#7314](elastic/eui#7314))

**CSS-in-JS conversions**

- Converted `EuiContextMenu`, `EuiContextMenuPanel`, and
`EuiContextMenuItem` to Emotion; Removed `$euiContextMenuWidth`
([#7312](elastic/eui#7312))
