Unable to open 'track selector' in synteny view after v2.13.0

[cmdcolin]

This code in hierarchical track selector expects a registered view model with the pluginmanager

jbrowse-components/plugins/data-management/src/HierarchicalTrackSelectorWidget/model.ts

Lines 104 to 106 in ac53708

	view: types.safeReference(
	pluginManager.pluggableMstType('view', 'stateModel'),
	),

but the v2.13.0 release tried to sneakily extend the view types without registering with the pluginmanager

jbrowse-components/plugins/linear-comparative-view/src/LinearComparativeView/model.ts

Lines 83 to 89 in ac53708

	views: types.array(
	model.views(self => ({
	scaleBarDisplayPrefix() {
	return self.assemblyNames[0]
	},
	})),
	),

this causes a error when doing view.activateTrackSelector for "view 1" or "view 2"
