IE: Unspecified Error when making a selection with images in the editor

[tmonahan]

This problem occurs when <META content="IE=7.0000" http-equiv="X-UA-Compatible"> is included in the HTML for the page. See 'IE unspecified error.html​' for a reproducible test case.

• Copy IE unspecified error.html​ into the _samples folder and open in IE.
• Insert a smiley and make a selection by starting the selection at the end of the editor contents.

Problem: an unspecified error occurs.

This is related to ticket #9034 and requires a similar fix. A proposed solution is provided in the attached patch.

Replying to garry.yao:

Hi Garry, In the provided fix, the moveRangeToPoint function always calls moveToPoint() on textRng, Previously it was called on rngEnd in the onHover function. Could this cause unexpected behavior?

The above is a valid review, post-fixed with [7556].
