/**
* The default `umask` set by Emscripten is 0777 which is too restrictive. This has been updated
* in https://github.com/emscripten-core/emscripten/pull/22589 but is not available in the stable
* version of Emscripten yet. In the meantime, we'll apply a workaround by setting the umask via
* `auto_prepend_file` PHP directive.
*
* Once the Emscripten update is available, a new version of Playground is released using the
* updated Emscripten, and the Playground dependency is updated in the app, this workaround can be removed.
