feat(textarea): set the real cursor position

[aymanbagabas]

This makes the textarea bubble set the real cursor position on update. This need the new "ferocious" renderer to work.

i wonder if it would make more sense to do this in the cursor pkg? 🤔

then it could be used on both textarea, textinput, and others 🤔

We would still need to tell the cursor the offset, otherwise it won't work with inline programs.
