Theme can't be changed for ipywidgets and solara.Markdown widget

[egormkn]

Hello!

Changing theme with ThemeToggle does not apply to ipywidgets and solara.Markdown widget. They always use the theme that was applied during the initial page load. Here is an example page:

import textwrap

import reacton.ipywidgets as rw
import solara


@solara.component
def Layout(children):
    dark_effective = solara.lab.use_dark_effective()
    return solara.AppLayout(children=children, toolbar_dark=dark_effective, color=None)


@solara.component
def Page():
    with solara.AppBar():
        solara.lab.ThemeToggle()

    rw.Button(description="Some button")

    rw.IntText(value=7, description="Some int:", disabled=False)

    rw.HTMLMath(value=r"$\text{Some equation:}\ \int f(x) dx$")

    solara.Markdown(
        textwrap.dedent(
            r"""
            # This is a title

            ## This is a subtitle
            This is a markdown text, **bold** and *italic* text is supported.

            ## Math
            Also, $x^2$ is rendered as math.

            Or multiline math:
            $$
            \int_0^1 x^2 dx = \frac{1}{3}
            $$

            """
        )
    )

UPD: I tried to create an example on app.py.cafe, but ipywidget styles seems to be broken there.

Hey @egormkn!

Thanks a lot for reporting this. I think it's interesting that on solara.dev it seems like solara.Markdown body text does change theme, while titles, etc. don't. Either way, I believe I found the issue and will open a PR to fix it.
