Designer image export crops off-screen graph data

[ThatOtherAndrew]

Describe the bug
When using "Save as PNG" or "Save as SVG" on large table graphs in Designer, anything that is off-screen does not get rendered, making the feature not particularly useful over just taking a screenshot.

To Reproduce
Steps to reproduce the behavior:

1. Go to the Designer tab
2. Pan to a position such that a table is partially cut off
3. Click on "Save as PNG"
4. Note how only part of the table is visible in the rendered image of the graph

Expected behavior
I expect to be able to see the full graph

Environment (you can view the current version under Settings):

• Operating System [e.g. Windows]: Windows
• Surrealist Version [e.g. 1.2.0]: 1.11.2
• SurrealDB Version [execute "surreal version"]: 1.1.1 for windows on x86_64

Issue still present for me in version 1.11.3
