Shift-selecting lyrics doesn't work with last word

I can shift-click to select all of the elements between the current selection and the shift-clicked element. This works in most cases for lyrics as well, but not with the final word of the piece. I can select any other range, but not the last word.

For example, I attached a simple sheet with four notes and the lyrics "this is a test." I can click on 'this' and shift-click 'a' to select 'this is a'. But if I click 'this' then shift-click 'test.', only 'test.' is selected.

It's not a big deal, but seems like a bug.
