Steps to Reproduce

1. click refresh button several times
2. run VisualVM, do a heap dump of the application, check the number of NoDOM object

Current Result

the number of NoDOM objects increases after each refresh

Expected Result

• there should be no NoDOM since the shadow elements have a parent component
• the number of NoDOM object should not increase and should be released

Debug Information

• The following cases don't cause the bug

          <forEach items="@init(vm.numbers)">
              <apply template="test"/>
          </forEach>
          <template name="test">
              ${each}
          </template>
  

          <forEach items="@init(vm.numbers)">
              <choose>
                  <when test="false">
                      <div style="color:blue">${each}</div>
                  </when>
                  <otherwise>
                      <div style="color:orange">${each}</div>
                  </otherwise>
              </choose>
          </forEach>
  

Workaround

        <forEach items="@init(vm.numbers)">
            <if test="@init(each % 2 eq 0)">
                <div style="color:blue">${each}</div>
            </if>
            <if test="@init(each % 2 ne 0)">
                <div style="color:orange">${each}</div>
            </if>
        <forEach items="@init(vm.numbers)">
