Breaking changes

• WithStatusLabel now sets field invalid state for consistent visual feedback
  Commit · Pull request · Issue

  Previously, withStatusLabel() only updated the status label but did not set the field's invalid state, resulting in inconsistent visual feedback where fields would not show the red background indicator for validation errors. This fix ensures that withStatusLabel() also delegates to the binder's handleValidationStatus() method, which properly sets/clears the field's invalid state through handleError()/clearError(). This provides consistent visual feedback (red background + status label) across all validation scenarios: - Required field validation - Custom validator failures - Conversion errors - Multiple validators

• Add aria-hidden="true" to hr component by default
  Commit · Pull request · Issue

  The "hr" element is announced as "Horizontal Splitter" by screen readers (e.g., VoiceOver on macOS), but in most cases it's used for visual purposes only. Adding aria-hidden="true" by default improves accessibility by preventing screen readers from announcing it. Users can still override this if needed by removing the attribute.

• Add Image constructor for byte array content
  Commit · Pull request · Issue

  Add a convenience constructor to Image class that accepts byte array content and an image name, simplifying the creation of images from in-memory data.

Fixes

• Set Content-Length header in InputStreamDownloadHandler (#22558)

  InputStreamDownloadHandler now properly sets the Content-Length HTTP header when provided in DownloadResponse, enabling browsers to display download progress and allowing TransferProgressListener implementations to calculate accurate progress percentages.
