For the Matrix and the Table Visuals (and others), tooltips simply show the value of the item over which the Pointer hovers. The behaviour of the tooltips differs from PBI Desktop to Browser in Term...
I would like to have tooltips available for matrices and slicers to display additional variable information. For example, a slicer may include a user name, but I would also like to display the employee id. However, concatenating these values interferes with the slicer selection. Additionally, I would like to hover over a field in the matrix and display addition information about that variable row.
