🐛 Bug Report

💻 Repro or Code Sample

at Edge's new tab page, we got lots of Cannot read properties of undefined (reading 'dispose') error messages in our log

{
	"stack": "TypeError: Cannot read properties of undefined (reading 'dispose')\n    
    at v.refreshAllViews 
    at v.handleChange 
    a......",
}

don't throw this exception

😯 Current Behavior

💁 Possible Solution

why not use "?.dispose" here?

fast-element/templating/repeat.js

    refreshAllViews(templateChanged = false) {
        //
        if (viewsLength === 0) {
           //
        }
        else {
            //
            for (i = 0, itemsLength = removed.length; i < itemsLength; ++i) {
                removed[i].dispose();
                // ^^^^^^^^^^^
            }
        }
    }
