On Power BI embedded report (based on azure workspace) I see the following behaviour on my slicers.
The slicers contain relatively long list of items so that they require scroll.
Multiple item selection is enabled in the slicers.
When the user selects a couple of items in the higher part or the list, the slicer will automatically scroll somewhere unrelated down the list. What is more problematic is that the slicer doesn't allow to scroll up again to the top of the list.
The slicer goes again to the top of the list if the user interacts with other visual in the same page of the report.
When the user what's to slice the data often this bug produces a painful expericence.
