…cs HTML Fixes #1481 When copying content from Google Docs, BR tags between paragraphs were being converted to newlines, which then got wrapped in empty paragraphs during normalization. This caused extra spacing between pasted content. The fix detects BR tags that appear between block-level elements and skips them during deserialization, while preserving BR tags within inline content. Co-authored-by: Ziad Beyens <[email protected]>

SummarySuccessfully fixed the issue where multiple consecutive BR tags between blocks weren't creating the expected number of empty paragraphs. Changes Made:
The fix correctly handles the scenario you described where 2 BR tags between paragraphs should create 2 empty paragraphs instead of being merged into a single paragraph with newlines. |
When Google Docs has multiple BR tags between paragraphs, each BR should create its own empty paragraph. Updated the isBrBetweenBlocks function to look for the nearest non-BR siblings instead of just immediate siblings. Added comprehensive tests for 2, 3, and multiple consecutive BR tags.

</b>So you need a function to know whether it's an actual line break in a paragraph vs. an empty paragraph. You can do that by looking up the parent (not siblings!) |

✅ Implementation CompleteSuccessfully refactored the BR tag handling logic to use a simpler parent-based approach as requested. Key Changes:
Test Results:
The implementation now correctly handles the Google Docs use case where BR tags between block elements should become empty paragraphs, while preserving BR tags within text content as line breaks. |
- BR tags inside P or SPAN elements remain as line breaks - BR tags with adjacent text nodes at the same DOM level become line breaks - Standalone BR tags inside structural elements become empty paragraphs - This correctly handles Google Docs HTML where BR tags between blocks should become empty paragraphs Co-authored-by: Ziad Beyens <[email protected]>

The fix detects BR tags that appear between block-level elements and skips them during deserialization, while preserving BR tags within inline content.
