Freeze when trying to move schema nodes around

[matterpale]

Description

After running the basic schema view query (match $x sub thing;) in a database with a small schema, I try to move things around to get a nicely structured visualization. Within a few seconds, TypeDB Studio freezes and can only be closed.

Environment

1. OS: Win10, Ubuntu 20.04.3 LTS
2. TypeDB version: TypeDB 2.5.0
3. TypeDB Studio version: 2.4.0-alpha-4

Reproducible Steps

1. In console, to a newly created database, commit a schema such as following:

   
   ## Matter Ontology

define

ATTRIBUTES

a_tag sub attribute, abstract, value string;

a_name sub a_tag;

a_category sub attribute, abstract, value string;

a_location sub attribute, value string, owns a_location;

occurs_at sub attribute, value datetime;

an_amount sub attribute, value long;

amount_unit sub attribute, value string;

ENTITIES

ConcreteEntity sub entity, abstract, # timespace-dependent physical entities owns a_location;

Object sub ConcreteEntity;

Process sub ConcreteEntity,         # a physical occurrence of an event
    owns occurs_at,
    plays duration:process;

Information sub entity, abstract; # entities with loose timespace dependence

RELATIONS

duration sub relation, owns an_amount, # length of time owns amount_unit, # time unit relates process;

RULES

rule location-transitivity: when { $x has a_location $y; $y has a_location $z; } then { $x has $z; };

2. Open that database in TypeDB Studio 2.4.0-alpha-4 and run the default  `match $x sub thing;`

3. Try to drag the schema nodes around the output tab.

## Expected Output

Smooth reorganization of nodes.

## Actual Output

Freeze (or crash?), in the sense that the only responsive part of the app is the query text field (plus, the OS context buttons).

We should test this in the new Studio.

This issue isn't resolved, but this pull request is a step towards that point. Further crashes occur when visualising this schema.
