I can reproduce it with `run-webkit-tests --ios-simulator fast/text/` against an iOS 15.4 SDK

Logging says: Cannot reconstitute installed font in GPU process: file://iNmEmOrYcGfOnT_0x600003184580#postscript-name=Ahem (Ahem) - { NSFontNameAttribute = Ahem; NSFontSizeAttribute = 16; }

Oh! This only happens in tests! It’s because we use InjectedBundle to install Ahem just for the web process. I wonder how to fix this 🤔 Surely we don’t want a GPU-Process-injected-bundle… Maybe I add testing-only code in the GPU process and only enable it in WKTR? 🤔🤔🤔
