Turn off Black tooltips on Matrix when using a Report Page Tooltip

hi, When I'm using a Report Page tooltip on a Matrix, it works fine on the Values, but on the Row and Column Headers it shows a Black tooltip which attempts to concatenate the name and title of the Row and Column headers.  I have a hierarchy on the rows of the grid, and in the tooltip it produces a string which is unreadable to the end user, it would be better to separate out each part of the hierarchy so that the user can see a single string for each level.  Alternatively it should be able to turn off th black tooltip and just use the default cream colour tooltip whcih is less intrusive. 

I have posted an idea here, https://ideas.powerbi.com/forums/265200-power-bi-ideas/suggestions/39691258-turn-on-report-page-tooltip-in-matrix-and-turn-of 

If you have another suggestion please let me know, or alternatively please vote for this idea. 

Thanks, Dan (Altius)
