- Fixed TypeError: Cannot assign to read only property 'position' of object
- Changed _loadPosition() to use Object.assign() instead of direct assignment
- Added null check for this.options?.position to handle both Foundry and test environments
- Updated fallback _AppBase class to store options in constructor for test compatibility
- Added comprehensive tests for _loadPosition() method
The error occurred because in FoundryVTT v14, ApplicationV2 freezes the options object,
making direct assignment to this.options.position impossible. Using Object.assign()
merges the properties instead, which works with both frozen and unfrozen objects.
