First line of wiki syntax in meeting notes is not rendered

To reproduce:

• install the meeting application (I tested on XWiki 6.4.5 but might be unrelated)
• create a meeting
• I only filled in description field, but I don't think it matters what you fill in
• fill in the notes of the meeting as follows:
  • use the wysiwyg of the meeting notes
  • add a table using the menu of the wysiwyg. Can be any table (default table 2x2 is fine)
  • it's very important that there is no other content before the table, not even a newline
  • fill in test data in the table (header row)
• save and view the meeting

Expected result:

• the table should be properly rendered, with a header and then the lines of the table

Actual result:

• instead of the table header, on the first row, we see the wiki syntax for the table header -> See the meeting notes field in the attached image

Please note that the issue is not only for tables, if you put a list in the meeting notes instead of the table, the first bullet of the list will not be rendered properly.
