--- Comment #1 from Fujii Hironori <Hironori.Fujii at sony.com> ---
CoordinatedBackingStore is created in the compositor thread, and stored in ImageBackingTextureMapperImpl::m_compositionState::backingStore.
https://github.com/WebKit/WebKit/blob/d3936e832f436bb9e3b552dd42948e5ba4239c67/Source/WebKit/Shared/CoordinatedGraphics/CoordinatedGraphicsScene.cpp#L159

However, ImageBackingTextureMapperImpl is destructed in the main thread.
