Home and End keyboard keys jump to start/end of the paragraph instead of the line

[FishieCat]

Normal behavior in Google docs, MS Word, Notepad, Notepad++, LibreOffice Writer, any HTML textarea or GitHub's issue reporting system is that the Home and End keyboard keys jump to start/end of the line in the text area.

In EasyMDE, instead they jump to the start/end of the paragraph, skipping visual line breaks.
