imgui assertion triggered when dragging Filter Palette panel to near bottom of window #943
Description
When you drag the Filter Palette panel down to near the bottom of the main window, it will crash with an imgui assertion: In window 'Filter Palette###Filter Palette/Scroller_518B409F': Must call EndChild() and not End()!
This only occurs if the Filter Pallet panel exits the view of the main window as shown in the screencast, every other panel is fine. BUT for example, when moving the whole Filter Graph panel with the Filter Palette still docked inside it, as soon as the Filter Pallet hits the same area it will cause the same assertion.
