### Godot version

v4.0.stable.official [92bee43ad]

### System information

Windows 10

### Issue description

This Godot 3 line

```gdscript
assert(r.hash() == {"a":1, "b":2}.hash())
```

was converted to this:

```gdscript
assert(r.hash() == {"a":1) #,"b":2}.hash())
```

For some reason `) #` is added after `1`.

### Steps to reproduce

Just converting Godot 3 project containing the line to Godot 4.

### Minimal reproduction project

// Returns the object that’s executing the function in the line.
// e.g. Passing the line "var roman = kieliszek.funkcja()" to this function returns "kieliszek".
