Fix #6382

not a big deal, but if you really want this to be a one-liner you can collapse it more; otherwise I'd write it as multiple lines. (same in add below)

Suggested change

	if(hadCluster) removeCluster(noSource); else removeNonCluster(noSource);
	(hadCluster ? removeCluster : removeNonCluster)(noSource);

Whew, looks like a lot of detailed testing went into figuring out all those conditions! Looks good - as discussed we should make a test before you lose track of what was done here, but if you want to publish the patch now and you're confident in your manual testing, feel free to go ahead with it! 💃

Thanks for the fix, folks.
Is there a way i can incorporate it into my Python Dash apps now, or must i wait for the next release of Dash?

@araichev Dash 2.7.1, released Monday, includes this fix. But in general, if there's a feature or fix in plotly.js that's been released but not included in Dash yet, you can grab the plotly.js bundle (or even build your own bundle, to get unreleased features or a slimmed-down bundle size) and put it in the assets/ folder of your Dash app https://dash.plotly.com/external-resources#example:-including-local-css-and-javascript

Or include a plotly.js CDN link in external_scripts https://dash.plotly.com/external-resources#adding-external-css/javascript
