Hi,

I have a problem that arises for the mapping configuration panel when a lot of fields are configured - the content of the scrollable panel is jumping around, especially when scrolling from bottom to top. It happens in Chrome but not in Firefox. Here's a video, I needed to add some additional fields to trigger the bug:

This is a known issues since ages now. Problem comes from ExtJS and nothing we could have done so far... Maybe it is better with ExtJS 7 on Pimcore X
