The webgl renderer reports an error when updating attributes of a Text element

[wang1212]

When using the webgl renderer, the program occasionally fails when updating the properties of a Text type element.

This is because no boundary condition judgment is made in the program logic.

export class TextDrawcall extends Instanced {
  updateAttribute(
    objects: DisplayObject[],
    startIndex: number,
    name: string,
    value: any,
  ): void {
+   if (objects.length === 0) {
+      return;
+   }

     // ...
  }
}
