Describe the bug
When creating an abstract, a toolbar is present to help the user insert markdown formatting codes.
When later editing the same abstract, the toolbar is missing, even though formatting with markdown still is possible.

To Reproduce
Steps to reproduce the behavior:

1. Create an event that allows abstract creation and modification
2. Create an abstract. Notice the presence of the tool bar
3. Modify the abstract. Notice the toolbar is missing

Expected behavior
A toolbar to give support to the users unfamiliar with markdown (or any formatted text for that matter) should always be present if a formatted text can be entered.
