Problems happend when trying to transform a VGroup object to another VGroup object

### Describe the error

I have two VGroup objects, which consisting of other VGroups and Mobjects, when I trying to apply a ReplacementTransformation to these two VGroup objects, some errors happend

### Code and Error
**Code**:

```
case_1_scene = VGroup()
case_1_scene.add(
case_1_vised_gird,
new_line,
case_1_explaination,
case_num_txt,
left_plug,
right_plug,
show_no_plug_on_left_right
)


del visited_grid_id
del vgrp_grid_line_list
vgrp_grid_line_list = (creat_grid_line(5, 5, 1, color=BLUE_E))[1]
case_1_overall_grid = (creat_blocked_grid_by_id(4,4,1,1,2))[1]
case_1_overall_vised_gird = (creat_visited_grid(4,4,1,
*(tuple(range(1,10))),
color=GREEN_E,
fill_color=GREEN_E,
fill_opacity=0.6
))[1]
case_1_overall_effect = VGroup(
vgrp_grid_line_list,
case_1_overall_grid,
case_1_overall_vised_gird
)

self.play(ReplacementTransform(case_1_scene, case_1_overall_effect))
```
If I change the code in the last few lines to this:
```
self.play(ReplacementTransform(case_1_scene, vgrp_grid_line_list))
self.play(Write(case_1_overall_effect))
```
Then it will run properly, and their will be a similar effect, but I just confused about that error

**Error**:
```

### Environment
**OS System**: Windows 10
**manim version**:manimgl
**python version**:3.8.6

此錯誤發生在 manimlib/mobject/types/vectorized_mobject.py 第733行，interpolate 因形狀不匹配而失敗。先檢查 VGroup 物件的內部結構以及 ReplacementTransform 如何映射 submobjects。查看兩個 VGroup 的資料陣列形狀，以了解為何 (6,1) 無法廣播（broadcast）到 (3,1)。執行提供的程式碼來重現該錯誤，然後追蹤插值邏輯。
