REPL: variable (re)definition doesn't work when exception in object construction

[freiit]

Version: v8.11.4, v10.9.0
Platform: all

$ node

class X { constructor() { throw "broken" }}
undefined
let b = new X()
Thrown: broken
b=1
ReferenceError: b is not defined
let b = 1
SyntaxError: Identifier 'b' has already been declared

Expected to be able overwrite b with "b=11" or redefine b with "let b=1".

Dupe of #22181 and #8309. It's working per spec, not a bug.
