Lit lifecycle console warning

[doodlewind]

Warning message thrown from pnpm test:

Element embed-block scheduled an update (generally because a property was set) after an update completed, causing a new update to be scheduled. This is inefficient and should be avoided unless the next update can only be scheduled as a side effect of the previous update. See https://lit.dev/msg/change-in-update for more information.

@DiamondThree any ideas?
