Symptoms
When editing an article, if you highlight something and then start typing (replacing that character or set of characters with something else), you get a Javascript error. We had this problem on version 4.2.13, and after upgrading to version 4.3.
The Javascript error is "range is null or not collapsed"
Cause
It is caused when you select content and type Enter. There's a Char 13 handler triggered on keypress, where getTextFromPreviousSiblingTextNodes(range) doesn't expect the range to select several characters (it expects a caret).
Affected Browsers:

Affects version:

Resolution
This was fixed in Version 4.3.7 of Confluence, and the bug report follows as https://jira.atlassian.com/browse/CONFDEV-10170
