[FIX] web_editor: remove unnecessary structuredClone

Commit [1] introduced a usage of `structuredClone` in 16.0 where
it is not supported. This was a mistake introduced by backporting
[2] from master to 16.0.

However, the `structuredClone` was not necessary in the first place
anyway, so this commit removes it.
