After creating link in editor the backspace removes paragraph text after the cursor in editor 4.0.3

Pressing the backspace key immediately after inserting a link causes undesirable behaviour.

Chrome 13 and 14:
After selecting some text (double-click a word), then adding a link with insert link, pressing backspace to remove the trailing link underscore actually causes all text after the cursor (up to the end of the paragraph) to disappear.

Firefox 6 and 7:
After selecting some text (double-click a word), then adding a link with insert link, pressing backspace to remove the trailing link underscore actually causes the cursor to move to the end of the paragraph.

Internet Explorer 8:
After selecting some text (double-click a word), then adding a link with insert link, pressing backspace to remove the trailing link underscore actually does nothing until you click it again and then it removes the entire link underline.

I often select entire words by double clicking them. This highlights the entire word (and, unfortunately the space following the word). Inserting a link into the selection causes the trailing space to also have a link underline. I found that when I press backspace to remove the underscore that the remaining paragraph to the right of the cursor disappears (Chome 14).

Reproduce:

3. Select Insert->Link and choose another page in confluence, click Insert
   • Note that an extra space following the word is underlined
4. Press backspace to remove the space
   • Note that the paragraph following the cursor has vanished
