Bug? Highlight does not get toggled from the beginning of the sentence.

Hi Alexis,
I'm really happy with your plugin.
However, there seems to be a bug: when highlighting, the highlight does not get toggled from the beginning of the sentence, but only from the position of the cursor, to the end of the sentence.

I thought it used to be starting from beginning of the sentence, to the end, even if the cursor is positioned at any point in the sentence, but that's not how it works anymore. Bug?
Thanks
