Using method forwarding creates elements for up to 9 times

[lemonadee71]

When I replace this

html`
<div is-list keystring="id">
  ${project.$lists((lists) => lists.map(List))}
</div>
`

with

html`
<div is-list keystring="id"> 
  ${project.$lists.map(List)}
</div>
`

It creates List for 8-9 times each but mounts once. Nested is-list components are not affected, just the direct component passed with the hook.
