Caret position wrong on contenteditable="plaintext-only"

[0lumide]

When an element uses contenteditable="plaintext-only" instead of contenteditable="true" the caret position returned by Caret.js is always at the beginning of the element, instead of at the caret position.

Note:

"plaintext-only" is a non-standard value forcontenteditable on chrome.
