Initially:

Drop some file between upload collections:

Scrollbar is gone

Hi Vladi,

That's the expected behaviour. Initially the UploadCollection is empty, for which a min-height is applied to it:

.ui5-uc-content.ui5-uc-content-no-data {
    min-height: 20rem;
}

Once there are elements in the default slot (files were uploaded), that ui5-uc-content-no-data class is removed and the element is as tall as its contained children, which in this case is shorter than the inital height of 20rem, causing the page to shrink in height, therefore removing its scrollbar.

The component accepts dropping files in its header area which should be changed. It should only allow dropping in its 'drop-zone'.
