DashedVMobject not returning correct output

When trying to draw a dashed line with custom length (width), it returns the continous version of the line.

```python
projection_line = DashedVMobject(
Line(point_a, point_b).set_width(100).set_color(YELLOW)
)
```

Also tried:
```python
projection_line = DashedVMobject(
Line(point_a, point_b).set_width(100)
).set_color(YELLOW)
```

And:
```python
projection_line = DashedVMobject(
Line(point_a, point_b)
).set_color(YELLOW).set_width(100)
```
