Currently, Firefox Mobile reports as not supported by Coda, and that’s because Coda uses a non-standard function: [Document: caretRangeFromPoint() method - Web APIs | MDN](https://developer.mozilla.org/en-US/docs/Web/API/Document/caretRangeFromPoint)

Bug related to this has been open for 5 years now: [1550635 - window.document.caretRangeFromPoint is not supported in Firefox](https://bugzilla.mozilla.org/show_bug.cgi?id=1550635)

Can usages of this be removed from the Coda codebase so that Coda follows web standards?
