- [x] Added automated test coverage as appropriate for this change.
When reading file as Data URL, CHUNK_SIZE must be divisible by 3, otherwise
the resultant string, made by concatenating chunks, will not be a valid Base64
encoded Data URL. Also Windows do not support reading sliced files as data
URLs, so we need to set chunk size equal to file size.
