Can’t use with reusable blocks

We’re not able to edit stackable blocks inside reusable block areas. Doing so breaks the block with a ‘This block has encountered an error and can’t be previewed’ and outputs the following console error messages:

TypeError: Cannot read property 'setAttribute' of null from

{
	key: "updateSidebarPanelTab",
	value: function(e) {
		var t = this.containerDiv.current.closest(".components-panel");
		t.setAttribute("data-ugb-tab", e),
		t.closest(".edit-post-sidebar").classList.add("ugb--has-panel-tabs")
	}
}

Cannot read property 'querySelector' of undefined from
this.getActiveTabPanelContainer().querySelector(".components-panel__body:nth-child(".concat(e + 1, "):not(.is-opened) .components-panel__body-toggle"))
