Lexxy remove empty lines on pasting texts

[AbdullahMedhat]

When pasting plain text, Lexxy converts it through marked (markdown parser):

  #pasteMarkdown(text) {                                                                                   
    const html = k(text);  // k is the marked library                                                      
    this.contents.insertHtml(html, { tag: [ Fn ] });                                                       
  }                                                                                                        

The marked library (v16.4.1) is called with default options, which means:

1. breaks: false (default) - Single newlines become spaces, not
   tags
2. Standard Markdown behavior - Empty lines between paragraphs collapse into single paragraph boundaries

In Markdown, consecutive empty lines don't produce multiple
tags or empty paragraphs - they just
separate paragraphs.

Example of what happens:
Line 1

Line 2

Line 3
Becomes:

Line 1

Line 2

Line 3

(No empty paragraph between Line 2 and Line 3)

To fix this, Lexxy would need to call marked with { breaks: true } or use a custom renderer.

This is expected behavior — Lexxy uses the marked library for markdown parsing, and standard Markdown collapses consecutive blank lines into paragraph separators. This is by design rather than a bug. If you need to preserve exact whitespace, consider pasting as HTML rather than plain text.
