Sometimes the Maps component is destroyed before it completed initialization, throwing an unhandled javascript exception:

TypeError: Cannot read properties of undefined (reading 'dispose')

I believe this is the problematic javascript in the component:

            dispose() {

                super.dispose();

                this._fBuilder.dispose();

                this._provider = undefined;

            }

From this snippet, we see that _fBuilder is only set part way through the map load:

            buildFeatures() {

                this._fBuilder = new GoogleProvider.Feature.FeatureBuilder(this);

                this._features = this._fBuilder.features;

                this._fBuilder.build();

            }

Adding a null check around this._fBuilder.dispose() would prevent this unhandled exception
