Level viewport toolbar buttons on the right side are collapsed even if the viewport has enough width

The following worka round works :

float SLevelViewportToolBar::GetTransformToolbarWidth() const
{
...
#if 0
//		float ViewportToolBarWidth = static_cast<float>(GetCachedGeometry().GetLocalSize().X);
#else //workaround
		float ViewportToolBarWidth = static_cast<float>(GetCachedGeometry().GetLocalSize().X) * DpiScale;
#endif

1. Set Windows DPI scaling on display setting to 150%
2. Launch the ue5.4 editor
3. Drag the edge of the level viewport to make it narrower
4. Observe tool button behavior on level viewport
5. Launch the ue5.5 editor
6. Drag the edge of the level viewport to make it narrower

Result:

Buttons on the right side are collapsed even if the viewport is wide enough
