`dx` charts flickering on every update within a panel

[jnumainville]

Description

dx charts are flickering on every update within a panel, even with memoization

Steps to reproduce

Run the following code

from deephaven import ui
import deephaven.plot.express as dx
from deephaven import agg

iris = dx.data.iris()

@ui.component
def create_chart():
    return dx.histogram(iris, x="SepalLength")

@ui.component
def flickering_memo():
  chart = ui.use_memo(lambda: create_chart(), [])
  text, set_text = ui.use_state(False)

  return [
    ui.button(text, on_press=lambda: set_text(not text)),
    chart
  ]

output = flickering_memo()

Then click the button

Expected results

Button changes value but chart does not change at all

Actual results

Chart quickly flickers

It's worth noting that the flickering is because of @ui.component

This does not flicker:

from deephaven import ui
import deephaven.plot.express as dx
from deephaven import agg

iris = dx.data.iris()

def create_chart():
    return dx.histogram(iris, x="SepalLength")

@ui.component
def flickering_memo():
  chart = ui.use_memo(lambda: create_chart(), [])
  text, set_text = ui.use_state(False)

  return [
    ui.button(text, on_press=lambda: set_text(not text)),
    chart
  ]

output = flickering_memo()
