TYPO3 Core

I've experienced this behavior of the CSH popup of a content element (the one triggered when you hover the field name and the mouse cursor becomes a "?" and you click:

• a small popup is opened on the left upper corner of the editing panel of TYPO3
• it seems there is no closing button and no way to close it apart from exiting the record or reloading the page by other means.
• if you click on other fields it may happen that different CSH remain open at the same time - see attached file - and overlaps; this also leads to weird behaviors (clicking again on a previous opened CSH might not work)
