Context doesn't update when fetching from a namespace

I'm having some trouble getting a context to be provided then read in a child component properly. At the top-most component, the context is defined, but perhaps because of the import order, it doesn't seem to re-update the context later? When the reading function si called, it only reads it as 'foobar' and doesn't change. Here is the schematic:

Right-click context menu onto another widget

I'd like to try and add a Solara right-click context menu onto a Plotly FigureWidget (FigurePlotly instance), but I have no idea how to disable the generic context menu and override with my own. Do you have any suggestions on how to get started with this?

FastAPI/nginx deployment issues, virtual kernels not served correctly?

currently, my app is deployed in a FastAPI context with a load balancer (nginx). however, it appears to be mismanaging the virtual kernels (i.e. somehow users get into other user's state), or it seems to restore them somehow from a previous virtual kernel as an example, a user cannot open two tabs of the app or refresh the page -- it seems to just break it entirely, and sometimes plots/etc will just appear out of nowhere. could you give me some further insight into deploying the app so i can avoid these issues?

any upcoming plans/existing ways to create guided tour functionality (solara)?

i'm interested in creating a guided tour for my app. are there any sort of upcoming plans to try and implement something like this, or would there be a way i could leverage something like this as a vue component to implement it? not sure exactly how to include/import the vue library within solara's context and get started with it, so any help/guidance would be appreciated

Plotly FigureWidget axes do not reset ranges within solara's render context

Upon applying an effect to set autorange=True to a figure with autorange='reversed', the Figure does not return to the original axes orientation. I'm wondering what happens behind the scenes here for the render when the use_effect is triggered. I can upload a ipynb with its expected behaviour within a jupyter context vs its behaviour in solara. The partial code (can give complete if needed). plotstate contains 2 reactives for flipx and flipy.

    def create_fig():
        z, cmin, cmax = perform_binning()
        fig = px.imshow(z.T,
                        zmin=cmin,
                        zmax=cmax,
                        origin="lower",
                        color_continuous_scale="inferno")
        return fig
