Tests using matrix authorization (or permissions tables similar to the used in this configuration) are presenting some issues relates to scrolling.

I have only been able to reproduce it in Mac (in a Linux VM seems to work) but when clicking in permissions outside the current view, the scrolling the element is not checked (but no error is launched), causing the test to fail downstream when the expected permission is not set.

Besides, tests in which elements with specific overflow styles (such as the "Add Credentials Dialog", used for example in CreateSlaveTest#newSlave are also problematic.
