I don’t know, if this is a bug or a feature and how it was in the previous versions. But for me it is a bug.
First open a test case with several lines of pages, wizards and modules. Expand all lines and select not only the modules, but all lines (modules and content of the modules). I select the first line and then select the last line while press shift key. After selecting the lines delete them.
My expectation was that the modules were deleted from the test case. But in the case, that the content was also selected, the content of the modules were deleted too.
Is it possible to attach a screenshot? I think that would be easier to understand.
