What is the maximum file size allowed by Upload/Html5File?

Is there a maximum file size that can be uploaded using the Upload/Html5File components?

The app just hangs for some time and the view resets if the file is over 2GB. Works fine for smaller files.

There shouldn’t be a limit. Upload sizes can be limited by server configurations and also application code; if you’re loading the uploaded file to memory, you might be limiting the size like that. It could also be a bug in the component or the framework - for this case, a reproducible example and a ticket would be nice.
