Bug description:
"The Obsidian Web Clipper inserts double newlines (\n\n) between each line of code when clipping code blocks from certain websites. This appears to be related to how specific sites structure their code block HTML."

Steps to reproduce:

Navigate to the danielabaron.me article (problem URL above)
Clip the article to Obsidian
Open the clipped note in source/edit mode
Observe that code blocks have \n\n between each line instead of single \n

Expected behavior:
Code blocks should preserve original formatting with single newlines between lines (as happens with the webcrunch.com article)
Actual behavior:
Extra blank lines appear between every line of code in clipped code blocks
Environment:
