Offline PDF export with many points not working #6108
The PDF is downloaded when clicking the corresponding button.
The download prompt appears so that you are able to select the location of the file, but a message "download / Failed - Network error" is displayed after the download supposedly finishes.
Live demo with steps to reproduce
I tested also the same on Firefox, and it is able to handle the download.

This turned out to be an issue with data URL lengths in Chrome, limited to ca 2MB. Changed the code to use Blob API if available for large files, will otherwise try to fall back to export server if enabled.
This issue will show up in PDF before the others because of the large size that comes with the format.
