[Animated GIF] Bug
Steps:
1. Go to <a href="http://n12v.dev/2-way-data-binding/">http://n12v.dev/2-way-data-binding/</a>
2. Inspect the first video, <video width="216" height="48" poster="/2-way-data-binding/temperature-converter.png">
3. Double click on "216"
4. Press Option-Up
Expected:
Value changes to "217", cursor stays where it was.
Actual:
Value changes to "217", cursor stays jumps to the beginning of the text field.
An error is thrown:
IndexSizeError: DOM Exception 1: Index or size was negative, or greater than the allowed value.
setEnd - EditingSupport.js:267
handleEditingResult - EditingSupport.js:267
keyDownEventListener - EditingSupport.js:289
Note that modifying height on the very same element works as expected. Although, it causes the DOM path bar to blink.</pre>
