Change List/Tile Views Scrollbar Size

Hey folks.

Does anybody know an easy way to override the size of the scrollbar which comes with an List or TileView in UMG?
Even though the exposed ScrollbarStyle contains the “Thickness” property, it just gets completely overridden by an SBox height override which is set with a hardcoded value of 16.0 by epic in their engine code for STableViewBase:

const FOptionalSize ScrollBarSize(16.f);
// ...
SNew(SBox)
.HeightOverride(ScrollBarSize)
[
	ScrollBar.ToSharedRef()  // <- actual scrollbar (created with user style from UMG), but unable to grow size
]

(https://github.com/EpicGames/UnrealEngine/blob/5.4/Engine/Source/Runtime/Slate/Private/Widgets/Views/STableViewBase.cpp#L100)

For me this doesn’t make any sense. And since this is also written in a non-virtual base class method, its pretty ugly to circumvent (except by creating a new c++ view and providing an external scrollbar from slate)

Am I missing something or is this implementation just flawed?

Cheers

Have the same problem. Watching this space to see if someone has any updates.

Same problem here and it seems to be that ugly since at least 6 years.
