Uploads larger than 2GB fail instantly

### Steps to reproduce

1. Configure a matrix-synapse installation with nginx to allow for uploads larger than 2GB.
2. Attempt to upload a file with a size above 2GB using the Element desktop app.
3. The upload will fail instantly without ever displaying a loading bar. Error message "Upload Failed The file 'filename' failed to upload." with filename being whatever file you tried to upload.
4. Uploads of files up to 1.99GB will not fail this way. If matrix-synapse or nginx are set to lower limits, the upload will fail, but the client will first display a loading bar.
5. The web app is not affected. Could be a memory limitation with Electron.
