The detection is triggered on first load, and in IE8 the
inserted value doesn't equal the value already in the textarea field.
That's possibly due to whitespace or encoding differences,
but they have the same character length.
Tried fixing this by whitespace removal, didn't work:
if((original || '').replace(/[\s\t\n\r]/g, '') != (value || '').replace(/[\s\t\n\r]/g, '')) {
In the end, we're already detecting changes through a 5s interval
triggering the save() method on the editor if the field is focused.
The impact of this removal is that after inserting an image,
it'll take a few seconds for the change detection to kick in
(and thus highlight the "save" button and ask for confirmation
when navigating away without saving).
