Actual result confirmed on Windows 10 (64-bit), Firefox Developer Edition 61.0b12 (64-Bit). In the quoted HTML, when I change <span> tags to <p> tags, only one line is selected.

Since in the HTML

    <p>abc def<br>ghi jkl</p>

only one line is selected on triple-click, performing a line break via the CSS

    .element:before {
        content:     "\A";
        white-space: pre;

should prorably result in the same behavior.

Just came across this, apparently it's still happening.

Went to the following page:

  1. Scroll down a bit to "Example #1 password_hash() example"
  2. In the box showing the PHP code, triple-click the line with "echo password_hash ... etc." to select just that line
  3. CMD-C or CTRL-C to copy the highlighted line.
  4. In a text-editor, CMD-V or CTRL-V to paste
  5. The pasted text will also include the code comments ("We just want to hash... etc.")

MacOS Catalina (10.15 (19A583)), Firefox 69.0.3 (64-bit)
