Hi guys.
We have found that In IE10, deleting dot points across multiple tab levels can cause the browser to crash.

Given the attached example, at least 3 behaviours can be demonstrated by making the following selections(including all text on the line) and then pressing delete:

• Dot Point 5.1 to 5.4, this will remove the items. Leaving an empty dot point at the same tab level.
• Dot Point 5.1 to 6, this will NOT remove the items and the cursor will move to the start of the Dot Point 6.1 text.
• Dot Point 5.1 to 6.1 (or even 6.2), the items will remain highlighted and the browser will "crash"
• Dot Points 5.1 to 7, this will NOT remove the items and the cursor will move to the start of the Dot Point 7.1 text

I have attached a video of the above scenarios which was recorded on 5.1 but has been replicated on 5.5.3 using the SDK.

Cheers
Mark.
