0.24.16

Major Features

• CSS/Selectors: add Dart-engine support for interactive and form pseudo-classes, including :hover, :active, :focus, :focus-visible, :focus-within, :enabled, :disabled, :checked, :required, :optional, :placeholder-shown, :valid, and :invalid, with new unit and integration coverage.
• Form Controls: add Dart-side <select> support with value/selectedIndex, focus and blur handling, required/multiple/disabled state, option and optgroup handling, and native menu rendering; improve <label> activation and default button/select UA styling.

Bug Fixes

• Rendering/Widget: preserve auto-height shrink-wrap for widget-hosted WebF content inside bounded flex and tooltip layouts; add regression coverage.
• Rendering/Inline: honor border-radius when painting inline backgrounds for inline spans.
• Form Controls: improve checkbox and radio checked-state synchronization across Dart/Blink paths, fix checkbox baseline alignment in inline formatting contexts, restore placeholder color behavior, and tighten default form-control typography and disabled-state styling.
• DOM/Focus: make generic elements focusable via tabindex, and fix focus/blur state propagation for selector matching and related events.
• Selectors/DOM: improve attribute selector and querySelector fallback matching for case-insensitive HTML attributes and live form-control values.
• Bridge/NativeValue: accept integer tags by coercing them to doubles during native value conversion.
