In a Code Block, double-click works incorrectly. Everywhere else, you double-click to select by word, and triple-click to select by paragraph. In a Code Block, I double-click as I am trained to do, and I select what I want to select, then when I release I am surprised that the entire Code Block is selected. Sometimes it takes me several tries to copy/paste one line of text in a "how to" Code Block whose express purpose is to provide text for me to copy/paste.

This aberrant behavior is highly frustrating.
