It ought to have adjusted the cursor internally for emacs mode.
It's hard to say exactly how the widget should behave from insert mode
exactly but this patch also fixes select-in/a-word to select further
words when invoked repeatedly from emacs mode. Note that
select-in-shell-word can't unfortunately do that even from vi mode.
I've also tried to consider weird combinations of
virangeflag, invicmdmode() and region_active but may have missed one.
Note that select-in-shell-word will select forwards in some
circumstances which might be unexpected for a backward-kill- widget.
Sorry for taking so long to reply to this.
