Thread:VisualEditor/Feedback/"Preformatted" type not accepting line breaks!

When you open up a new Preformatted section, it immediately shows the greyish box with dashed/dotted border and one can type into this with the right font, etc. How is one supposed to type multiple lines within the preformatted section? Hitting return/enter simply exits the preformatted section and puts the cursor right under it. Even copying and pasting a bunch of text from web-browser/text-editor(vim/emacs/gedit/etc.) does not preserve the line breaks and puts all the copied text on a *single* line
