Description Said Abou-Hallawa 2023-04-04 12:26:29 PDT 
The change 262547@main adds the assertion `ASSERT(!m_size.isEmpty());` in all the ShareableBitmapConfiguration constructors. However one of them is called when decoding a null ShareableBitmapHandle in UIProcess which has m_size.isEmpty() true. The corresponding ShareableBitmapConfiguration was created with the default constructor in WebProcess.
