When editing a page in IE11, Confluence is unable to add a full stops (multiple full stops) at the last line in Editor.

Steps To Replicate

1. Create a new page
2. Press the 'dot' key to add full stop (not working)
3. Write a word 'test' and press enter
4. Write a word 'last line' and press the 'dot' key to add full stop (not working)

Workaround

• Copy and paste the 'dot' / full stop from somewhere else
• Go back one character to the left before the last line and add the 'dot'
