MBS-9105: Multiple answers in the Mootimeter word cloud are not displayed

[tholudwig]

Description
Multiple entries can be made in the word cloud, if permitted. This makes sense from a didactic point of view. However, multiple entries are not currently displayed as such in the student's view.
When deleting a multiple entry, only one of the entries is correctly displayed. From the user's point of view, however, it looks as if the deletion will not take place.

**Aim

1. to emphasise multiple entries. This could be by displaying the words multiple times or by using a "2x" icon next to the word.

• Idea 1:
  

• Idea 2:
  

2. deletion mechanism must be adapted accordingly.

Testing

1. create Mootimeter activity with word cloud.
2. allow multiple entries
3. make multiple entries as a user.

• Before patch:
  • Multiple nomination is not displayed.
  • Delete a multiple nomination --> is carried out in the background but not displayed.
• After patch
  • Multiple nominations are highlighted
  • Deletion process is clearly highlighted
