Adding the date macro to a page in WYSIWYG mode will remove content after the macro

[aubincleme]

Steps to reproduce :

• Install Task Manager pro 3.2
• Go in the sandbox page and edit the page in wiki mode
• At any point in the page, add the date macro
• Observe that the outline of the macro (the blue box) encapsulates not only the date, but also the rest of the content below the macro
• Save and view
• Observe that any content after the macro is gone

This probably comes from some issues when closing macro tags.

(tested on XWiki 14.10.6 ; I believe this also works on XWiki 14.10.x)
