Fix out-of-bounds inspection of 2d plots

Fixes #1090

Hi,
I'm the person who opened the issue that you so quickly fixed with this commit.
As I was writing in the issue, after this fix everything works fine: the REPL does not give errors anymore and hovering with the mouse over the agent makes the correct popup appear. However, I now noticed what seems to be a warning.
In order to reproduce it, I do the following. I open with VSCode the folder containing the .jl and .toml files corresponding to the MWE and the environment of the opened (and now closed) issue. At the bottom, before even starting the REPL, in the VSCode section "Problems", the following message appears:

Possible method call error. 

or, if I right click on it and choose copy,

[{
	"resource": "/home/damiano/projects/testing/testing.jl",
	"owner": "_generated_diagnostic_collection_name_#1",
	"code": "IncorrectCallArgs",
	"severity": 2,
	"message": "Possible method call error.",
	"source": "Julia",
	"startLineNumber": 24,
	"startColumn": 19,
	"endLineNumber": 24,
	"endColumn": 69
}]

The corresponding line is underlined in blue by VSCode.
Do you know what this is? Is it an Agents.jl problem, a Makie.jl problem, a VSCode problem, none of those?
Thanks.
