There are a number of issues when copying, cutting, and pasting code within a code block using Chrome, as well as general navigation. For example, I am trying to format some XML. I want to copy the whitespace before one element and paste it in front of another element to get the alignment to display.

• If I right-click and select copy on the whitespace, the selected text becomes unselected when the context menu appears and I can't copy it. However, I can copy the text with Ctrl-C.
• If I right-click and select paste, the first time I do this nothing happens. The second time I do it, an underscore is inserted (in contrast, if I do the same thing in IE9, a single space is inserted, regardless of how many spaces I had copied; that is also annoying, but in another way) and the interface locks up. I literally can't do anything in the editor. I have to either save or cancel and start editing again to be able to continue working.
• If I use Ctrl-V to paste, it skips the not inserting, then inserting an underscore thing: the whole edit interface locks up up from the get-go.
