The example Composition XML file saved by clicking the button 'Save to file' is truncated

[linforestzhang]

When getting an example Composition from a large template (14k+ xml lines), the example Composition XML file saved by clicking the button 'Save to file' is truncated to 5,951 xml lines. The xml content in the link of the the button 'Save to file' is complete. The xml content on the webpage is also complete so manual copying would be temoprary workaround for this issue.

And the canonical JSON file is similiarly truncated from 18,477 to 7,600 json lines.

Both the Structured JSON file and the FLAT JSON file are normal.
