Server-side selectize labels have incorrect escaping

[jcheng5]

It looks to me like the values are correct, it's just the labels that are over-escaped.

from shiny import reactive
from shiny.express import input, ui, render

ui.input_selectize("x", "Server side selectize", choices=[], multiple=True)


@reactive.effect
def _():
    ui.update_selectize(
        "x",
        choices=[f"Foo & {i}" for i in range(10000)],
        selected=["Foo & 0", "Foo & 1"],
        server=True,
    )

@render.express
def foo():
    input.x()

Does NOT appear to be a problem for R. Attempted repro
