[BUG] Using Bookmark to reset drill down in Matrix does not work in WebService

Hi, I am trying to build a reset button, which shall collapse / uncollapse a hierarchy in a matrix to a certain layout. If a user is clicking on the button the same state shall be displayed. In Power BI Desktop, this can be achieved using a bookmark (selected visual, data) on a reset button and everything works as expected. When uploading the pbix to the WebService a click on the reset button expands all nodes to certain level. Please look into this :)
