Merge #11054

11054: fix #11049 by removing double trimming r=Veykril a=Heinenen

The `unwrap_trivial_block()` removes the braces around trivial blocks (as the name suggests). This violates the precondition of `update_expr_string()` which removes the first and the last non-whitespace character and thus expects braces to still exist around all blocks.
