UI: Toggling vertical scrollbar causes background to resize

[SamuelPull]

when toggling between table view and card view, and when items (projects, subprojects, worfklowitems) are filtered by search, scrollbar may appear/disappear which causes the background to resize. looks almost like the screen is flashing.

After analysis, this seems to be an expected behaviour in the browser. It could be cosmetically fixed by adding overflow-y: "scroll" into body css, but then we would have vertical scrollbar in the app at all times. Therefore I am closing this issue for time being.
