 # WYSIWYG Editor Refactoring Progress Summary
 
+## Latest Updates
+
+### Selection Highlighting Fix ✅
+- **Issue**: "Paragraphs are not highlighted consistently, headings are always highlighted"
+- **Root Cause**: The `shouldUpdate` method in `dees-wysiwyg-block.ts` was using a generic `.block` selector that would match the first element with that class, not necessarily the correct block element
+- **Solution**: Changed the selector to be more specific: `.block.${blockType}` which ensures the correct element is found for each block type
+- **Result**: All block types now highlight consistently when selected
+
+### Enter Key Block Creation Fix ✅
+- **Issue**: "When pressing enter and jumping to new block then typing something: The cursor is not at the beginning of the new block and there is content"
+- **Root Cause**: Block handlers were rendering content with template syntax `${block.content || ''}` in their render methods, which violates the static HTML principle
+- **Solution**: 
+  - Removed all `${block.content}` from render methods in paragraph, heading, quote, and code block handlers
+  - Content is now set programmatically in the setup() method only when needed
+  - Fixed `setCursorToStart` and `setCursorToEnd` to always find elements fresh instead of relying on cached `blockElement`
+- **Result**: New empty blocks remain truly empty, cursor positioning works correctly
+
+### Backspace Key Deletion Fix ✅
+- **Issue**: "After typing in a new block, pressing backspace deletes the whole block instead of just the last character"
+- **Root Cause**: 
+  1. `getCursorPositionInElement` was using `element.contains()` which doesn't work across Shadow DOM boundaries
+  2. The backspace handler was checking `block.content === ''` which only contains the stored content, not the actual DOM content
+- **Solution**:
+  1. Fixed `getCursorPositionInElement` to use `containsAcrossShadowDOM` for proper Shadow DOM support
+  2. Updated backspace handler to get actual content from DOM using `blockComponent.getContent()` instead of relying on stored `block.content`
+  3. Added debug logging to track cursor position and content state
+- **Result**: Backspace now correctly deletes individual characters instead of the whole block
+
+### Arrow Left Navigation Fix ✅
+- **Issue**: "When jumping to the previous block from the beginning of a block with arrow left, the cursor should be at the end of the previous block, not at the start"
+- **Root Cause**: Browser's default focus behavior places cursor at the beginning of contenteditable elements, overriding our cursor positioning
+- **Solution**: For 'end' position, set up the selection range BEFORE focusing the element:
+  1. Create a range pointing to the end of content
+  2. Apply the selection
+  3. Then focus the element (which preserves the existing selection)
+  4. Only use setCursorToEnd for empty blocks
+- **Result**: Arrow left navigation now correctly places cursor at the end of the previous block
+
 ## Completed Phases
