                    WebKit::PDFPlugin::installPDFDocument()

           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified

Big Sur AppleSilicon Debug WK2 EWS bots seem to be frequently seeing an assertion failure attributed to fast/replaced/frame-removed-during-resize.html. This test is not crashing on trunk bots, so there is probably another test running before this one that is triggering this crash.

CoreGraphics PDF has logged an error. Set environment variable "CG_PDF_VERBOSE" to learn more.
