Describe the bug
CRLF line breaks are not supported, leading to incorrect display of markdown document content. Additionally, the destroy method does not remove elements with the class mu-float-wrapper, resulting in excessive DOM node initialization and causing the page to freeze.

To Reproduce
Steps to reproduce the behavior:

1. Go to a markdown document with CRLF line breaks.
2. Load the document in Muya.
3. Observe the incorrect display of content.
4. Call the destroy method and check for remaining elements with the class mu-float-wrapper.

Expected behavior
The content should display correctly without issues related to line breaks. The destroy method should remove all relevant elements from the DOM.

Actual behavior
The content displays incorrectly due to CRLF line breaks, and elements with the class mu-float-wrapper remain in the DOM after destruction, causing performance issues.
