Backslash completion broken in debugger in 1.12

[projekter]

When entering into REPL mode while debugging, the backslash tab completions don't work under Julia 1.12. The following example works in 1.10, but is broken in 1.12:

julia> using Debugger
julia> fn() = nothing
julia> @enter fn()
In fn() at REPL[2]:1
>1  fn() = nothing
