      Description

      Reproducible sample:

      <zk>
          <label multiline="true">
          1. Open tree node 1, 3, 7, 15, 31, 63, 127, 255
          2. Navigate to page 2 then navigate back to page 1
          3. Close tree node 255
          4. Should see tree node 4, 8 (bug if not seeing).
          </label>
