Bug description

Diagrams larger than the current example will display incorrectly in two ways: 1) will be occluded on the right, and 2) will be occluded on the bottom if they are too long

How to reproduce the bug

To reproduce the width issue:

Go to https://alshedivat.github.io/al-folio/blog/2021/diagrams/

Drag the diagram to the right.

I could not reproduce the height issue with sequenceDiagrams (the mermaid diagram used in the example). However, things break down if you use other types.

Using the below will lead to a diagram that gets cut at the bottom, even though this diagram renders fine in other places (such as markdown preview and here, see below):

```mermaid
classDiagram
    note "From Duck till Zebra"
    Animal <|-- Duck
    note for Duck "can fly\ncan swim\ncan dive\ncan help in debugging"
    Animal <|-- Fish
    Animal <|-- Zebra
    Animal : +int age
    Animal : +String gender
    Animal: +isMammal()
    Animal: +mate()
    class Duck{
        +String beakColor
        +swim()
        +quack()
    }
    class Fish{
        -int sizeInFeet
        -canEat()
    }
    class Zebra{
        +bool is_wild
        +run()
    }
```

It renders fine here:

classDiagram
    note "From Duck till Zebra"
    Animal <|-- Duck
    note for Duck "can fly\ncan swim\ncan dive\ncan help in debugging"
    Animal <|-- Fish
    Animal <|-- Zebra
    Animal : +int age
    Animal : +String gender
    Animal: +isMammal()
    Animal: +mate()
    class Duck{
        +String beakColor
        +swim()
        +quack()
    }
    class Fish{
        -int sizeInFeet
        -canEat()
    }
    class Zebra{
        +bool is_wild
        +run()
    }

Somehow the generated svg is ending with style="max-width: 684.6133422851562px;". Probably fixing this will solve the problem.

I noticed that too, the value on my end is equally arbitrary (and different). I tried tinkering with the css to no avail, and after some reading, it seems that the property is being determined elsewhere.

I tried to check if I could fix it quickly, but it seems to need a "magical" solution.
