Testing Procedure

There are multiple scenarios where you can find this. You can go to the Material Entry gallery and whenever you focus one entry you see the scrollbar flash on the right.

If you go to the label gallery and go through the MaxLines cases you will also see a scrollbar flash.

With this change, that should not be visible anymore
