Uno: [WASM] Hiding VerticalScrollBar in ScrollViewer also hides HorizontalScrollBar

[peternary]

Current behavior

If you set VerticalScrollBarVisibility="Hidden" in a ScrollViewer then the HorizontalScrollBar also becomes hidden, though you can still interact with it by clicking in the appropriate area.

Expected behavior

HorizontalScrollBar appearance should be independent of VerticalScrollBar.

How to reproduce it (as minimally and precisely as possible)

In the sample here you can see two sample uses of ScrollViewer, the only difference being that the top one has VerticalScrollBarVisibility="Hidden" set.

In the top sample notice that the HorizontalScrollBar is also hidden, though clicking and dragging in the area you would expect it to appear works.
