Gosling react component does not work with React's StrictMode

[john-conroy]

I ran into errors attempting to use Gosling's react component in an application with StrictMode on. I experienced these errors with both Gosling v0.17.0 and v1.0.0 and React v18.3.1. Disabling StrictMode allowed the component to render.

Cannot read properties of null (reading 'destroy')
Cannot read properties of null (reading 'removeChild')

Hi, I think I can replicate this in the editor:

// editor/index.tsx

/* ... */

root.render(
    <StrictMode>
        <BrowserRouter>
            <Route component={Editor} />
        </BrowserRouter>
    </StrictMode>
);

Seems to be mostly related to HiGlassComponent2. @sehilyi Does this look like something within Gosling scope or in Higlass?

HiGlass is the source of this issue since it uses deprecated React syntax (a message about UNSAFE_componentWillMount). It should be addressed in our new version that removes the HiGlass dependency #1094

I will note this in #1094 and close this issue.
