Research direction
Investigate the export functionality in ui grid that uses canvas.toDataURL. Look for any security checks that may be causing the SecurityError in IE11. Consider using a workaround such as setting crossOrigin attribute or handling the error gracefully. The issue is old; verify if it still reproduces in recent versions of the grid or if it was fixed. Check if there are any related commits or PRs that address this.
