Cross-highlighting affecting a stacked column chart that changes the y-axis scale triggers a bug that prevents the column height from resetting aftet the cross-highlighting ends and the y-axis scale switches back. The new column height will macth the column hight of the "grayed-out" columns that were behind the highlighted columns. The data labels are not affected by this bug and will be floating where they should be as if the columns have reset. Clicking nearly anywhere on the affected visualization will usually cause the columns to reset to their heights to the correct hieghts. This bug exists in an embedded environment, on app.powerbi.com, and in Power BI desktop (fully updated). It happens with the stacked column visual and the stacked column combo visual. This bug was first reported to me on 06DEC2019 and was first noticed in an embedded report. I was able to easily recreate this with a fresh report in Power BI desktop and on app.powerbi.com.
