HTML highlighting only highlights the last selected element

[njx]

1. Open the Getting Started file
2. Start Live Preview
3. Select several paragraphs in the HTML

Result: Only the last paragraph is highlighted (or, if your selection includes some whitespace before or after the first/last paragraph, the whole body is highlighted).
Expected: Highlight all elements within the selection.

Medium priority to @gruehle, although maybe this is move to backlog.

Hi, is this still current or has it been closed. Could you attach the file for download, and I will look at the coding.
