Remove Transparency or Add White Background to Visuals' Breadcrumb Menu

When we publish a report, users are reporting that clicking the breadcrumbs on a visual to Share, Set Alert, Add a Comment, Export, etc. results in the menu overlaying on other text/items on the canvas, making it hard to see/read the menu options because the menu background is transparent. It would be helpful in improving users' experience and eliminating this problem for them if the background of this breadcrumb menu could be made white so when it is active, the user can easily see the options available.
