Ravenous Bugblatter Beast of Traal
When editing a post, if I highlight a word I already typed and hit the button or press the key for bold, italics, underline or strikethrough, the paragraph(s) after it (but not the current paragraph) all gain that formatting. It also does it for color, font, and size.
This is a paragraph with no editing I typed before putting bold, etc. in the above paragraph.
