Description:
If you insert a comment and scroll the document (with the mouse wheel) before entering the text into the comment, after start of typing the document become not focused to the comment, so you do not see, if or what are you typing.

Steps to Reproduce:
1. Open an empty document
2. Write some text to more pages
3. Focus on text on some page on the end of the document and insert a comment
4. Scroll up with mouse wheel to the previous pages (or top of the document) so you do not see the comment.
5. Start typing,

Actual Results:
The document is still focused on the last position you have scrolled to with the mouse wheel.

Expected Results:
The document view should be focused back to the comment where the cursor is. 


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
I do not know, if the actual result is intended, but if you have a huge document(e. g. more than 10 pages), and you want to check/look at some text of the document, when you are writing the comment, typing again into the comment makes you fuzzy as you do not know, where exactly are you typing. If there are also many comments, it takes really much time to find the right one.
