Describe the bug The '.desktop' file built into the AppImage includes the '--no-sandbox' option on the 'Exec=' line. This added option somehow breaks the filename being passed in by the '%U' parameter on that line.

To Reproduce Steps to reproduce the behavior:

1. Run the AppImage with "/path/to/drawio.AppImage --no-sandbox /path/to/file.drawio"
2. Drawio opens to dialog asking to create a new drawing or open an existing one as if the file parameter isn't passed.
3. Close drawio
4. Run the AppImage with "/path/to/drawio.AppImage /path/to/file.drawio"
5. Drawio runs and opens the file specified.

Expected behavior The '.desktop' file included in the AppImage should allow for the application to be opened with a file parameter.

draw.io version (In the Help->About menu of the draw.io editor):

• draw.io version 19.0.2

Desktop (please complete the following information):

• OS: Ubuntu 20.04

Additional context The full '.desktop' file from the AppImage. I'm assuming this is generated in one of the build steps since I can't find it in the repo.

This issue is still occurring. I'm now running draw.io version 20.8.16. Every time I upgrade, I have to fix the '.desktop' file.

I have since moved to using the snap instead of the appimage. The problem doesn't occur in the snap. Possibly related to #1490?
