Fixed

• MD041 (first-line-heading): Fixed multiline HTML detection for headings

  • Replace manual HTML parsing with centralized ctx.html_tags() parser
  • Correctly handles nested HTML elements with multiline attributes
  • Fixes Issue #152: No longer incorrectly flags headings when preceded by multiline HTML

• MD037 (no-space-in-emphasis): Improved warning message clarity

  • Truncate long emphasis text in warning messages to prevent display issues
  • Long emphasis spans are now shown with ellipsis for better readability

Performance

• MD005 (list-indent): Eliminated O(n²) complexity by pre-computing parent relationships

  • Pre-compute parent list item relationships during initial parsing
  • Reduces algorithmic complexity from O(n²) to O(n) for deeply nested lists
  • Improves performance for files with complex list structures

• Optimized link/image regex patterns to prevent catastrophic backtracking

  • Added atomic grouping and possessive quantifiers to regex patterns in lint_context.rs
  • Prevents regex engine from exponential backtracking on pathological inputs
  • Improves parsing speed for files with many links and images

Changed

• MD033 (no-inline-html): Refactored to use centralized HTML parser
  • Removed 109 lines of broken find_multiline_html_tags() function that detected 0 multiline HTML tags
  • Replaced two-pass approach (single-line regex + multiline detection) with single-pass using ctx.html_tags()
  • Now correctly detects all multiline HTML tags (previously missed 100% of them)
  • Follows pattern from MD041 refactoring for consistency
  • Preserves all existing filters (code blocks, kramdown, comments, etc.)

Added

• Comprehensive MD005 test coverage
  • Added 21 new edge case tests for list indentation detection
  • Updated unicode test to verify dynamic parent relationship detection
  • Ensures robustness for nested and complex list structures
