BUG-Passing a function which returns a dictionary to chart.properties does not always work

[arcanaxion]

Description

Per title, I receive this warning:

Warning 1: chart.properties (tp_TpExPr_create_chart_properties_selected_type_TPMDL_1_0) must be a dict.

How to reproduce

from taipy.gui import Gui, Markdown
import pandas as pd

x_range = range(-10, 11)
df = pd.DataFrame({
    "X": x_range,
    "Y": [x*x for x in x_range],
})

def create_chart_properties(selected_type):
    properties = {
        "x": "X",
        "y": "Y",
        "type": selected_type,
    }
    print(properties)
    return properties

types = ["bar", "line"]
selected_type = types[0]

md = Markdown(
"""
<|{df}|chart|properties={create_chart_properties(selected_type)}|rebuild|>

<|{selected_type}|toggle|lov={types}|>
""")

Gui(md).run()

Steps to reproduce:

1. Toggle to "line" -- no immediate changes to the chart
2. Refresh page
   a. Observe that the chart changed to "line"
   b. Also, the warning above is in the terminal
3. Toggle back to "bar" -- no immediate changes to the chart
4. Refresh page
   a. Observe that the chart did not change back to "bar"
   b. The warning is printed again

Expected behavior
The chart should switch between "bar" and "line" as the toggle control is toggled.

I guess the need to refresh may be related to Avaiga/taipy#466, but I don't know about the warning. Must the properties property be a literal dictionary and not a function return value, even when used with rebuild?

[FredLL-Avaiga]

as for now, properties don't allow chart rebuild.
I can fix the warning (which is a separate issue) but it won't fix this issue.
