Ensure renderRoot exists before first update by sorvell · Pull Request #4387 · lit/lit

sorvell · 2023-11-10T20:23:09Z

Fixes #4268. Ensures renderRoot exists before first update. It's created upon first connection by default (so that it exists before controllers' hostConntected), but this change supports early calls to performUpdate/enableUpdating without
depending on connection.

Fixes lit#4268. Ensures `renderRoot` exists before first update. It's created upon first connection by default (so that it exists before controllers' `hostConntected`), but this change supports early calls to `performUpdate`/`enableUpdating` without depending on connection.

The size of lit-html.js and lit-core.min.js are as expected.

AndrewJakubowicz

Thank you. This looks good to me. Just some small nits.

The size of Lit will also need to be updated per the comment: #4387 (comment)
