wrapped inline alien: incorrect highlighting in chromium

If an inline alien gets word wrapped, then selecting it leads to incorrect highlighting.

Reproducing: make a <tt> ... </tt> with enough content to word wrap. Select with the mouse (or use CTRL+A).

In chromium, the highlighter erroneously draws a box enclosing the first character and the last (see first attachment).

In firefox, the highlighter erroneously highlights to the end of the first line only (see second attachment).
