Description:
The comment textbox can't be resized or moved in edit mode, however it can be changed in show mode. Not understand the logic of that. When I type something into a commentbox I want to be able to resize it in Edit Mode.

Steps to Reproduce:
1. Open Calc
2. Insert a comment CTRL+ALT+C or Right Click context menu Insert Comment
3. Type something into the comment textbox 
4. Try to change the shape and position of the textbox. (Not possible)
5. Exit the comment box. Right Click the Cell with the comment and select Show Comment. Now it's possible to change the position and size

Actual Results:  
It isn't possible to change size and position of the textbox in edit mode (but in Show mode)

Expected Results:
In Edit Mode you edit. Editing means also resizing and re-positioning of the textbox. Resizing and re-positioning under show mode is intuitive and unproductive 


Reproducible: Always
