An assertion may fire with certain window sizes when opening https://ccameron-chromium.github.io/hdr-jpeg/index.html. After 284617@main, GraphicsContextCG::drawNativeImageInternal() has two calls to CGContextStateSaver::save(). The first one is called before clipping the context to partially display the image. The second one is called before setting the headroom of an HDR image. If these two calls happen in the same session, the second call will fire the assertion `ASSERT(!m_saveAndRestore);` in CGContextStateSaver::save().
