All braces escaped in generated code

[ronnodas]

Whenever I use an assist that inserts some code, all the braces in it are escaped with slashes. For example, using "Generate foo function" on let bar = foo(); produces:

fn foo() -> _ \{
    todo!()
\}

rust-analyzer version: 0.3.1850-standalone

rustc version: rustc 1.76.0 (07dca489a 2024-02-04)

relevant settings: using VS Code extension, not sure which setting could affect this
