Breaking: #68571 - Removed method ElementBrowser->getMsgBox¶
The removed method
ElementBrowser used table based styling.
The method has been removed since we have better means to display this kind of messages: FlashMessages or Callouts.
A fatal error will be thrown if the method
getMsgBox is used.
Third party code using the removed method.
Remove the call to the method and replace the message with a FlashMessage.
